I have a pgfplotstable: I would like to create a reading out example for a value, with the red lines and the framed cell. This could look like this then: How could I do that best way? My immediate idea would be a TikZ-spy. But maybe there's a completely different/easier way. %\documentclass[paper=a5]{scrarticle} %\usepackage[margin=14mm, showframe]{geometry} \documentclass[margin=5pt, varwidth]{standalone} \usepackage{diagbox} \usepackage{colortbl} \usepackage{pgfplotstable} \pgfplotsset{compat=1.18} \usetikzlibrary{spy} \pgfplotstableread[col sep=comma]{ n, k, 0.1, 0.2, 0.3, 0.4 1, 0, 1.1, 1.2, 1.3, 1.4 1, 1, 2.1, 2.2, 2.3, 2.4 2, 0, 2.1, 2.2, 2.3, 2.4 2, 1, 3.1, 3.2, 3.3, 3.4 2, 2, 4.1, 4.2, 4.3, 4.4 3, 0, 3.1, 3.2, 3.3, 3.4 3, 1, 4.1, 4.2, 4.3, 4.4 3, 2, 5.1, 5.2, 5.3, 5.4 3, 3, 6.1, 6.2, 6.3, 6.4 }{\mytable} \begin{document} \pgfplotstabletypeset[ every head row/.style={before row=\hline, after row=\hline}, columns/k/.style = {% k column column name={\diagbox{$k$}{$p$}}, column type={|>{\cellcolor{pink}}c|}, },% ]{\mytable} \begin{tikzpicture}[ spy using outlines={rectangle, magnification=1, connect spies} ] \spy [blue, width=2cm, height=1cm] on (0,1) in node [fill=white] at (3,0.5); \end{tikzpicture} \end{document}

I am using fontspec in order to write in Times New Roman. The authors of cited literature are always set in small caps. This initially made problems because the font has no small caps, but I solved those by googling and finding a solution on stackexchange. However, the small caps don't work when they are also bold, e.g. in a section heading. This is my MWE: \documentclass[12pt]{article} \usepackage[utf8]{inputenc} \usepackage[ngerman]{babel} \usepackage{fontspec} \setmainfont{Times New Roman}[ SmallCapsFont={TeX Gyre Termes}, SmallCapsFeatures={Letters=SmallCaps}, ] \begin{document} \section{Regel von \textsc{Ritschl}} Regel von \textsc{Ritschl} \end{document} Which produces: As you can see, the small caps in the text body work just fine. In the heading, however, the small caps are not set bold. When using the ebgaramond package, this issue does not occur and everything looks as it should and very pretty, but, of course, in Garamond: I actually prefer the looks of Garamond but unfortunately I have to write in Times New Roman. Does anyone know how this could be fixed? Thanks in advance! If relevant: I am using LaTeX with LaTeX workshop in VSCode on a MacBook Air.

I'm running into a problem that Beamer is behaving exactly as it should :). I am using a solution that begins a frame with \begin{frame}<beamer:0|handout:0> and then recalls the frame with \againframe. The purpose of this approach is to get miniframes and frame numbers to increase, as desired here: How to adapt miniframes to increasing pagenumber in overprint However, any theorems or other numbered environments do not have their numbers increased. I can increase them manually, but I don't want to keep track of manually increasing counters.

I'm trying to use SQLite and cannot get it to even initialize. I tried to follow the instructions at https://www.pragma-ade.nl/general/manuals/luametatex.pdf pages 701-702.

I have been tasked with designing a template for creating a tagged PDF that meets certain formatting requirements. The only major obstacle I have encountered is in generating a Table of Contents that meets these (rather stringent) demands. Normally, I would use tocloft for this; however, as it has been pointed out in other posts, this is currently not an option. I have tried working around this, but I must admit that I am out of my depth. Between the default settings and some things I have found on this forum, I have been able to get the ToC to a place that I like. There are three things I still can't figure out: I would like to set the font (italic or boldface) for the chapters, sections, subsection, etc. I would like to force chapter titles to appear uppercase in the ToC. I need to add the word "Page" above the page numbers in the ToC, list of figures, and list of tables. I have a cheap workaround for (2) which is just to make a new command: \newcommand{\Chapter}[1]{\chapter[\MakeUppercase{#1}]{#1}} but this is quite stupid. To acheive (3), I write \makeatletter \newcommand{\pageheaderlabel}{ \hfill\makebox[\@pnumwidth][c]{Page}\par\smallskip } \let\old@starttoc\@starttoc \renewcommand{\@starttoc}[1]{ \pageheaderlabel \old@starttoc{#1} } \makeatother but this is quite hacky (and is slightly off-center). On a somewhat related note, I have been using titlesec as I normally would; e.g, \usepackage[rm, tiny, center, compact]{titlesec} \titleformat{\chapter} {\ifdefined\boldheadings\bfseries\fi\centering\normalsize} {\thechapter.}{1em}{\makeuppercase} \titlespacing*{\chapter} {0pt} {0pt} {20pt} and I have not encountered any issues, despite the fact it is currently marked as incompatible with tagging. If it is breaking something, I cannot tell what. If there are any known workarounds to achieve this without titlesec, that would be much appreciated.

I would prefer for all of the theorems in a document of mine to be written in slanted style rather than italic. The math symbols themselves should still appear in italic, only the written text should be slanted. In my opinion this adds to readability. Consider the following example taken from Qing Liu's Algebraic Geometry and Arithmetic curves, p. 71: Is there any easy way to do this for the whole document instead of changing every single theorem?

Here's a crazy proposition I am not sure is feasible: Create a tcolorbox (for instance in beamer) so that the box is automatically resized so that its content is balanced. Consider this code: \usepackage[skins]{tcolorbox} % for boxes \tcbset{ myblockbase/.style={ beamer, enhanced, no shadow, boxrule=1.2pt, arc=2.5mm, left=2mm,right=2mm,top=1.2mm,bottom=1.2mm, titlerule=2pt, coltitle=white, fonttitle=\bfseries\scshape, } } \newtcolorbox{myblock}[1]{% myblockbase, colframe=MidnightBlue, colback=MidnightBlue!10, colbacktitle=MidnightBlue, titlerule style={MidnightBlue!60}, title={#1}, } This creates a nice box I use for my slides. However, look at the attached image created as follows: \begin{myblock}{} \raggedright Notice the natural boundary conditions emerge naturally after integrating by parts! \end{myblock} Of course I could start playing with the width of the color box so as to get the right width in order to get both lines having more or less the same length. Would it be possible in any way to do this automatically? Is there a way to have some sort of iterative algorithm at the preamble that is computing the right width that the tcolorbox should take?

I have a 2×2 groupplot (where the first plot should be replaced by a title "Supertitle") with titles in boxes. These "title boxes" should all have the same width, and boxes in the same row should have the same height. I achieved this using \vphantom{} because I didn't find a better method. How can I configure the settings such that the entire groupplot has a width of \textwidth? And a horizontal space between the columns like \tabcolsep (or something similar)? Is there a elegant way to do this by package keys? (resizebox etc. would certainly work, but that would be less elegant.) Ideally, it should stay a groupplot. PS: I'm using DIN A5 format here, but that shouldn't matter if the keys are set correctly. \documentclass[paper=a5]{scrartcl} \usepackage[margin=14mm, showframe]{geometry} \usepackage{pgfplots} \usepgfplotslibrary{groupplots} \pgfplotsset{compat=1.18} \begin{document} \section{Plots with Titles and Supertitle} \pgfmathsetlengthmacro\plotwidth{0.5*\textwidth-\the\arraycolsep} \begin{tikzpicture}[font=\footnotesize] \begin{groupplot}[ % Grouupplot settings ================== group style={ group size=2 by 2, % 2 columns, 2 rows vertical sep=25mm, horizontal sep=15mm, }, % Styles applied to all subplots ============== width=\plotwidth, height=30mm, % Title Styles ========================== title style={% at={(0,1)}, xshift=-3ex, align=left, anchor=south west, inner xsep=2pt, draw, fill=none, text width=0.925*\pgfkeysvalueof{/pgfplots/width}, },% ] % Title (Row 1, Col 1) \nextgroupplot[ % I don't know how to get this box to the same height without this trick: title={\vphantom{Plot 0} \\ \vphantom{000} \\ \vphantom{000}}, title style={name=super}, hide axis, ] \addplot[draw=none, samples={0}]{x}; % Plot 0 (Row 1, Col 2) \nextgroupplot[title={Title 0 \\ 000 \\ 000}] \addplot{x}; % Plot 1 (Row 2, Col 1) \nextgroupplot[title={Title 1 \\ 2-111 \\ 3-111 \\ 4-111}] \addplot{x^2}; % Plot 2 (Row 2, Col 2) \nextgroupplot[title={Title 2 \\ 2-222 \\ 3-222 \\ \vphantom{4-111}}] \addplot{x^3}; \end{groupplot} %% Supertitle \node[font=\bfseries\Large] at (super){Supertitle}; \node[anchor=north west, draw=none, align=left,] at (super.south west){ Some notes \\ below Supertitle}; \draw[cyan, very thick, |-|] (group c1r2.west) -- +(\plotwidth,0) node[midway, below, fill=yellow]{plotwidth =\plotwidth}; %% This gives a 'Overfull \hbox ' warning ================== \draw[red, thick, |-|, ] ([yshift=5mm]group c1r2.west) -- +(2*\plotwidth,0) node[midway, above, fill=yellow]{2*plotwidth =\plotwidth}; \end{tikzpicture} \end{document}

I'm probaby doing something stupid in this example and I don't know if anyone would ever do this; but should it be okay to set up the head in the lua code and still start the sections in ConTeXt code? If all of this brief example is coded in lua and run as a .cld file, it works. But if split it and run as .tex file, it errors concerning the command option line. If remove the command option line or remove the set up head from the lua code section and declare it in the ConTeXt section as \setuphead[section][command={\MySectionLua}] it works. Is there a way to write the command option line to permit the context.setuphead to remain in the lua code? Thank you. The error is: ! Control sequence expected instead of undefined tex error > tex error on line 16 in file ./junk.tex: { command = [[mber %s Title: %s",nbr,ttl) <argument> { command = [[\MySectionLua %s",nbr,ttl) ) ]] }, <macro> \luat_start_lua_code_indeed #1\stopluacode ->\directlua {#1 \beginlocalcontrol \endgroup \endlocalcontrol } <line 3.16> \stopluacode 6 protected = true, 7 actions = function(nbr, ttl) 8 context("Number %s Title: %s",nbr,ttl) 9 end, 10 } 11 12 context.setuphead( 13 { "section" }, 14 { command = [[\MySectionLua]] }, 15 ) 16 >> \stopluacode 17 18 \startTEXpage 19 \startsection[title={Title One}] 20 Paragraph 21 \stopsection 22 \stopTEXpage 23 You injected something that confused the parser, maybe by using some Lua call. mtx-context | fatal error: return code: 1 \startluacode interfaces.implement { name = "MySectionLua", public = true, arguments = "2 arguments", protected = true, actions = function(nbr, ttl) context("Number %s Title: %s",nbr,ttl) end, } context.setuphead( { "section" }, { command = [[\MySectionLua]] }, ) \stopluacode %\setuphead[section][command={\MySectionLua}] \startTEXpage \startsection[title={Title One}] Paragraph \stopsection \stopTEXpage

I know there are several relevant questions on TeX Stack Exchange about nicely highlighting matrix multiplication, and some of them have excellent answers. I apologize if my question is a duplicate. I have managed to highlight the various entries manually, but it requires quite a bit of work. Is there a way to automate this procedure? \documentclass{article} \usepackage{amsmath, amssymb} \usepackage{xcolor} \usepackage[margin=1.5cm]{geometry} \begin{document} \section*{Matrix Multiplication} We want to compute the product \(AB\) for \[ A = \begin{bmatrix} 3 & 1 & -1 \\ -1 & 0 & 4 \end{bmatrix}, \quad B = \begin{bmatrix} 2 & 1 & 3 \\ -1 & 3 & 4 \\ 0 & 2 & 5 \end{bmatrix}. \] We can illustrate the multiplication as follows, highlighting each row of \(A\) and each column of \(B\): \[ \begin{array}{c@{\hspace{2em}}c@{\hspace{1em}}c} & \begin{bmatrix} \color{blue}{2} & \color{orange}{1} & \color{purple}{3} \\ \color{blue}{-1} & \color{orange}{3} & \color{purple}{4} \\ \color{blue}{0} & \color{orange}{2} & \color{purple}{5} \end{bmatrix} & \\[1em] % \begin{bmatrix} \color{red}{3} & \color{red}{1} & \color{red}{-1} \\ \color{green}{-1} & \color{green}{0} & \color{green}{4} \end{bmatrix} & = & \begin{bmatrix} \underbrace{\color{red}{3}\cdot \color{blue}{2} + \color{red}{1}\cdot \color{blue}{-1} + \color{red}{-1}\cdot \color{blue}{0}}_{\color{black}{5}} & \underbrace{\color{red}{3}\cdot \color{orange}{1} + \color{red}{1}\cdot \color{orange}{3} + \color{red}{-1}\cdot \color{orange}{2}}_{\color{black}{4}} & \underbrace{\color{red}{3}\cdot \color{purple}{3} + \color{red}{1}\cdot \color{purple}{4} + \color{red}{-1}\cdot \color{purple}{5}}_{\color{black}{8}} \\[0.5em] % \underbrace{\color{green}{-1}\cdot \color{blue}{2} + \color{green}{0}\cdot \color{blue}{-1} + \color{green}{4}\cdot \color{blue}{0}}_{\color{black}{-2}} & \underbrace{\color{green}{-1}\cdot \color{orange}{1} + \color{green}{0}\cdot \color{orange}{3} + \color{green}{4}\cdot \color{orange}{2}}_{\color{black}{7}} & \underbrace{\color{green}{-1}\cdot \color{purple}{3} + \color{green}{0}\cdot \color{purple}{4} + \color{green}{4}\cdot \color{purple}{5}}_{\color{black}{17}} \end{bmatrix} \end{array} \] Thus, the final product is \[ AB = \begin{bmatrix} 5 & 4 & 8 \\ -2 & 7 & 17 \end{bmatrix}. \] \bigskip \textit{Note:} \(BA\) is not defined because \(B\) is \(3\times 3\) and \(A\) is \(2\times 3\); the number of columns of \(B\) (3) does not match the number of rows of \(A\) (2).

My new keyboard writes ^ as ˆ, and overleaf doesn't recognize these the same way. Is there an alternative symbol in latex for writting powers and indexes or some way to make overleaf recognize ˆ as ^?

At the moment, I don't remember how to number the equations inside dcases , with the amsart class, without empheq, in order to assign a label to each one. \documentclass{amsart} \usepackage{mathtools} \begin{document} \begin{subequations} \begin{equation} \begin{dcases} 0 \le \frac{u+v}{2} \le 1 \\ 0 \le \frac{v-u}{2} \le 1 - \frac{u+v}{2} \end{dcases} \iff \begin{dcases} 0 \le u+v \le 2 \\ \label{Psojjn} 0 \le v-u \le 2 - (u+v) \end{dcases} \end{equation} \end{subequations} \end{document} Addendum: My desidered output.

I am writing a manuscript in revtex4-2, which is mostly in two-column format, but which has a (relatively meaty) section inside widetext. One quirk I've noticed, and which I would like to fix, is that one of the footnotes is inside that widetext, but it is being displayed in two-column mode, which looks rather ugly: How can this be fixed? I notice, in particular that the revtex4-1 guide says the following, \footnote in \widetext and table* environments improved. \footnotes in the \widetext or table* environments are now correctly placed and formatted. which would make one think that this was a problem in previous versions but should be fixed in RevTeX 4.1 and later. So what gives? Below is a minimal working example to produce the behaviour: \documentclass[% reprint, aps, pra, nofootinbib, ]{revtex4-2} \usepackage{lipsum} \begin{document} This is some two-column text. \lipsum[1-2] \begin{widetext} This is some one-column text, with a footnote.% \footnote{This is the footnote text, which is long enough to be just over one column wide.} \lipsum[1-8] \end{widetext} \end{document}

First, apologies if this question has been asked before. I'm trying to create an image of a particular circular domain, but my limited TikZ knowledge has made this quite challenging. I've searched for similar examples online without success. Any guidance would be greatly appreciated!

I am using various datatool-databases with sums of funding for different projects and years. My aim is to have a macro with which I can get the sum of either a type or a year. The problem with my approach is that I need to create a list of available databases first, which I can feed to \DTLsumforkeys. Neither \datatool_db_state:nnnn {requestedFunding-\pNumber} {\clist_put_right:Nn \l__project_list_requested_funds_clist {requestedFunding-\pNumber}} {}{} nor its non-expl3-command \DTLifdbexists {requestedFunding-\pNumber} {\clist_put_right:Nn \l__project_list_requested_funds_clist {requestedFunding-\pNumber}} {} is creating the proper list for \l__project_list_requested_funds_clist, which should be requestedFunding-A01,requestedFunding-A02,requestedFunding-B01. The list \l__project_list_requested_funds_clist is then meant to be used in the actual macro calculating the sums. \documentclass{scrartcl} \usepackage{datatool} \usepackage[ mode = match, propagate-math-font = true, reset-math-version = false, reset-text-family = false, reset-text-series = false, reset-text-shape = false, text-family-to-math = true, text-series-to-math = true, tight-spacing = true, group-minimum-digits = 4, group-separator = {,}, %table-format = 6, table-alignment-mode = format, table-auto-round = true, locale =UK, input-decimal-markers = {.}, output-decimal-marker = {.}, input-ignore={,}, parse-numbers = true ]{siunitx} \DTLnewdb{project} \DTLnewrow{project} \DTLnewdbentry{project}{number}{A01} \DTLnewrow{project} \DTLnewdbentry{project}{number}{A02} \DTLnewrow{project} \DTLnewdbentry{project}{number}{B01} \DTLnewrow{project} \DTLnewdbentry{project}{number}{Q01} \DTLnewdb{requestedFunding-A01} \DTLnewrow{requestedFunding-A01} \DTLnewdbentry{requestedFunding-A01}{type}{costs} \DTLnewdbentry{requestedFunding-A01}{sum-year1}{1000} \DTLnewdbentry{requestedFunding-A01}{sum-year2}{2000} \DTLnewrow{requestedFunding-A01} \DTLnewdbentry{requestedFunding-A01}{type}{staff} \DTLnewdbentry{requestedFunding-A01}{sum-year1}{1001} \DTLnewdbentry{requestedFunding-A01}{sum-year2}{2001} \DTLnewdb{requestedFunding-A02} \DTLnewrow{requestedFunding-A02} \DTLnewdbentry{requestedFunding-A02}{type}{costs} \DTLnewdbentry{requestedFunding-A02}{sum-year1}{1000} \DTLnewdbentry{requestedFunding-A02}{sum-year2}{2000} \DTLnewrow{requestedFunding-A02} \DTLnewdbentry{requestedFunding-A02}{type}{staff} \DTLnewdbentry{requestedFunding-A02}{sum-year1}{1001} \DTLnewdbentry{requestedFunding-A02}{sum-year2}{2001} \DTLnewdb{requestedFunding-B01} \DTLnewrow{requestedFunding-B01} \DTLnewdbentry{requestedFunding-B01}{type}{staff} \DTLnewdbentry{requestedFunding-B01}{sum-year1}{1001} \DTLnewdbentry{requestedFunding-B01}{sum-year2}{2001} % intentionally there is no entry for Q01 \begin{document} \DTLdisplaydb{project}\\ \DTLdisplaydb{requestedFunding-A01}\\ \DTLdisplaydb{requestedFunding-A02}\\ \DTLdisplaydb{requestedFunding-B01}\\ \ExplSyntaxOn \clist_new:N \l__project_list_requested_funds_clist \DTLforeach{project}{ \pNumber=number }{ % \DTLifdbexists {requestedFunding-\pNumber} % {\clist_put_right:Nn \l__project_list_requested_funds_clist % {requestedFunding-\pNumber}} % {} \datatool_db_state:nnnn {requestedFunding-\pNumber} {\clist_put_right:Nn \l__project_list_requested_funds_clist {requestedFunding-\pNumber}} {}{} } % Doublecheck: \clist_use:N \l__project_list_requested_funds_clist \NewDocumentCommand{\getSumOverviewFundsCurrent}{smm} { % #2: year % #3: type (staff, costs...) \str_if_eq:nnTF {#2}{all} { \DTLsumforkeys{% \clist_use:N \l__project_list_requested_funds_clist } {sum-year#3}% {\SumOverviewRequestedFunds} } {\DTLsumforkeys[\DTLiseq{\pType}{#3}][ \pType=type %{staff,costs,instrumentation,fellowships,globalfunds} ]{ \clist_use:N \l__project_list_requested_funds_clist } {sum-year#2} {\SumOverviewRequestedFunds}} \IfBooleanTF{#1} {\SumOverviewRequestedFunds} {\tablenum{\SumOverviewRequestedFunds}} } \ExplSyntaxOff \getSumOverviewFundsCurrent*{1}{staff} % expecting here: 3,003 \getSumOverviewFundsCurrent*{2}{staff} % expecting here: 6,003 \getSumOverviewFundsCurrent*{1}{costs} % expecting here: 2,000 \getSumOverviewFundsCurrent*{2}{costs} % expecting here: 4,000 \getSumOverviewFundsCurrent*{all}{staff} % expecting here: 9,009 \getSumOverviewFundsCurrent*{all}{costs} % expecting here: 6,000 \end{document}

I'm translating Kazakh problems for the Art of Problem Solving forum, and I faced an obstacle with this problem: It translates like: Aigerim and Batyrkhan play the following game. There is a board of size $2\times2024$ (2 rows and 2024 columns). They take turns, with Aigerim moving first. On her move, Aigerim places a horizontal domino on the board $\boxed{\phantom{a}}\boxed{\phantom{a}}$, covering exactly two squares. On his move, Batyrkhan places a vertical domino on the board $\begin{aligned} \fbox{\rule{0pt}{1.2em}\hspace{1.2em}}[0em] \fbox{\rule{0pt}{1.2em}\hspace{1.2em}} \end{aligned}$, also covering exactly two squares. A player who cannot make a move loses. (Dominoes may be placed only on empty squares.) Who wins if both players play optimally? and I don't know how to do the vertical domino without separation between the squares. AoPS doesn't support features like tikzpicture, so I need to come up with a different method.
