How can I add the numbers $k$ and $n-k$ as in the figure?

I am trying to typeset an empty matrix with a colored row or column. I know how to do it using tikz, but would rather not use it - if possible. I made some attempts, but the colored row (rectangle) overlaps the left bracket and is typeset below the right bracket. Do you have any suggestions? You can see my attempts below: \documentclass[10pt]{article} \usepackage[usenames]{color} %used for font color \usepackage{amssymb} %maths \usepackage{amsmath} %maths \usepackage[utf8]{inputenc} %useful to type directly diacritic characters \usepackage[table]{xcolor} \usepackage{nicematrix} \begin{document} \begin{equation*} % \begin{bmatrix} \rowcolor{red} \ & & \\ \ & & \\ \ & & \\ \end{bmatrix} % \qquad % \left[ \begin{array}{@{}ccc@{}} \rowcolor{green} \ & & \\ \ & & \\ \ & & \\ \end{array} \right] % \qquad % \begin{bNiceMatrix}[] \rowcolor{blue} \ & & \\ \ & & \\ \ & & \\ \end{bNiceMatrix} \end{equation*} \end{document} The output is:

Yes, another tex4ebook question. This time I am having issues with background images. The generated ePub simply has no image at all. Is it not possible at all?

I'm working on a long document that will eventually take the general form %<preamble stuff> \begin{document} \input{doc1} \input{doc2} \etc \end{document} And while writing it all, I want to separately run pdflatex on each of the doc1,doc2,etc, just to carefully think about each without all the surrounding mess. I successfully did that as illustrated by the "minimum working example" below, but that is itself somewhat of a mess. So I'm hoping you can suggest a simpler way to accomplish the same thing. I separated the <preamble stuff> into a separate file, which for our "mwe" is % --- preamtext.tex --- \documentclass[12pt]{article} \newcommand{\preaminp}{preamble text inputted} % --- other preamble commands, etc --- \newcommand{\spinor}[2]{\ensuremath{\left({{#1}\atop {#2}}\right)}} % --- end-of-file preamtext.tex --- And the "main" file, so to speak, is just % ---test.tex -- \input{preamtext} \begin{document} \input{doc1} %\input{etc} \end{document} % --- end-of-file preamtest.tex --- Finally, each doc1,doc2,etc is of the general form % --- doc1.tex --- \ifx\preaminp\undefined \input{preamtext} \begin{document} \newcommand{\preamend}{\end{document}} \else \newcommand{\preamend}{ } \fi Hello, world. This is a test, albeit a silly one: \spinor ab. \preamend % --- end-of-file doc1.tex --- So each such doc will check whether or not \preaminp is defined. If not, it will itself \input the preamble stuff, and insert a \begin{document} and \end{document} for a complete self-contained document. If \preaminp is defined, it does none of that. Bib stuff will be similalry handled, but not necessary for our mwe, though it does add to the overall mess introduced by this hack. Nevertheless, it does seem to work okay, i.e., pdflatex test.tex and pdflated doc1.tex both produce the same pdf file, illustrating the example \spinor command from the preamble. But is there any simpler way to accomplish this mess? Thanks.

I am currently working on a 3D surface plot in which both x-, and y-axis are logarithmic. The issue I am facing and why I am posting is that the measurements are too close to each other, and I hence end up with overlapping axis ticks on the x-, and y-axis. Is there a good way to transform individual ticks, bet it an odd/even selection, or directly picking out individual ticks and then shifting them?

I usually use the bropd package, which provides an automatic way to alternate different kinds of brackets with the \br command. They even automatically change size to accomodate their content. This greatly improves the readibility of large formulae. Here is a minimal example showing how it is supposed to work \documentclass[english]{article} \usepackage{bropd} \begin{document} \begin{equation} \br{\br{n+1}\br{\sum_{i=1}^n i+n\br{n+3\br{n+2}}}}^2 \end{equation} \end{document} Unfortunately, the \br command specifically is incompatible with the yathesis package I intend to use, which provides a very complete template for PhD theses, following the french legal requirements. A friend of mine suggested the following correction in a minimal example \listfiles{} \RequirePackage{bropd} \NewCommandCopy{\Br}{\br} \let\br\relax \documentclass[mainlanguage=english]{yathesis} \usepackage[T1]{fontenc} \begin{document} \begin{equation} \Br{\Br{n+1}\Br{\sum_{i=1}^n i+n\Br{n+3\Br{n+2}}}}^2 \end{equation} \end{document} It did repair the now \Br command in the sense that now it does produce brackets, which automatically match the size of their content. But it does not alternate anymore. The documentation of the bropd package does explain the implementation of the \br command but I am not savy enough to know how to proceed.

Is it possible to center align an arbitrary equation within an align environment (or similar), with equation numbers for each line? For example \begin{align} x & =y & w & =z \\ 2x & =-y & 3w & =\frac{1}{2}z \\ x&=1 (\mbox{center this line}) \end{align} Attempt 1 Using a sequence of two align. Requires manually adjusting spacing such as \setlength{\belowdisplayskip}{0pt} to avoid large gap, which may lead to inconsistent spacing \begin{align} x & =y & w & =z \\ 2x & =-y & 3w & =\frac{1}{2}z \end{align} \begin{align} x = 1 \end{align} Attempt 2 Use gather + aligned. But this approach does not give each line its own number. \begin{gather} \begin{aligned} x & =y & w & =z \\ 2x & =-y & 3w & =\frac{1}{2}z \end{aligned} \\ y = 1 \end{gather} Attempt 3 Use multispan. Equation of last line is too far. \begin{align} x & =y & w & =z \\ 2x & =-y & 3w & =\frac{1}{2}z \\ \multispan{4}{\hfill $y = 1$\hfill} \end{align}

I want to make a quantum circuit (with possibly quantikz) that starts in a maximally entangled state for which each tensor factor is partitioned. That is, I want to replicate some of the quantum circuits as below (from https://arxiv.org/abs/1911.06314, p26): I know quantikz has the command \makeebit[s]{l} (p13), but it seems like it's only possible to use it for the lines connecting Br and Bl on the right hand side, not both and not either side. I am looking for a way to at least replicate the right side of the figure, preferably also the left side and preferably using a package. Is that possible? A satisfactory answer would be: some command like \eebit that generates the drawn line as in the 'desired outcome' some alternative tensor graphing package that does the job I'd greatly appreciate your considerations and thanks in advance.

I tried to do it in two ways. first try: \documentclass{article} \usepackage{xcolor} \usepackage{titlesec} % Define the stripe color \definecolor{franjacolor}{RGB}{0,102,204} % ---- Custom macro: left stripe before number ---- \newcommand{\SectionLeftStripe}[1]{% % draw a small rule (stripe) on the left, aligned with the number \color{franjacolor}\rule[0.6ex]{1.2em}{1pt}\hspace{0.8em}% \color{black}#1% } % ---- Section format ---- \titleformat{\section} {\normalfont\Large\bfseries} % format of text {\SectionLeftStripe{\thesection.}} % number preceded by stripe {0.5em} % space between number and title {} % title text follows normally % ---- Section spacing ---- \titlespacing*{\section}{0pt}{3ex plus 1ex minus .2ex}{2ex plus .2ex} \begin{document} \section{Introduction} text text text text text text text text text text text text text text text texttext text text text text text text texttext text text text text text text text text text text text text text text text text text text text text text text texttext text text text text text text texttext text text text text text text text \section{Development} text text text text text text text text text text text text text text text texttext text text text text text text texttext text text text text text text text \section{Conclusion} text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text texttext text text text text text text text \end{document} Second try \documentclass{article} \usepackage{xcolor} \usepackage{titlesec} \usepackage{calc} % Define stripe color \definecolor{franjacolor}{RGB}{0,102,204} % --- Custom macro: left/right stripes with section number --- \newcommand{\SectionSideStripes}[1]{% \noindent % Left stripe \color{franjacolor}\rule[0.6ex]{1.2em}{1pt}\hspace{0.8em}% % Section number + title \color{black}#1% % Right stripe \hspace{0.8em}\color{franjacolor}\rule[0.6ex]{1.2em}{1pt}\par } % --- Section format --- \titleformat{\section} {\normalfont\Large\bfseries} % font and weight {\thesection.} % section number (with dot) {0.5em} % space between number and title {\SectionSideStripes} % macro for stripes % --- Spacing before/after section title --- \titlespacing*{\section}{0pt}{3ex plus 1ex minus .2ex}{2ex plus .2ex} \begin{document} \section{Introduction} text text text text text text text text text text text text text text text texttext text text text text text text texttext text text text text text text text text text text text text text text text text text text text text text text texttext text text text text text text texttext text text text text text text text \section{Development} text text text text text text text text text text text text text text text texttext text text text text text text texttext text text text text text text text \section{Conclusion} text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text texttext text text text text text text text \end{document}

I'd like to group my front matter entries together in the table of contents so that there is no vertical space between them. Here's my current code: \frontmatter \chapter*{Abstract} % Abstract here \setcounter{page}{1} \pagestyle{headings} \addcontentsline{toc}{chapter}{Abstract} \setcounter{secnumdepth}{3} \setcounter{tocdepth}{3} \tableofcontents \listoffigures \addcontentsline{toc}{chapter}{\listfigurename} {\let\cleardoublepage\relax \listofalgorithms} \addcontentsline{toc}{chapter}{\listalgorithmname} My current contents page looks like this: I'd like to keep all the rest of the spacing between chapters exactly as is, though move the abstract, list of figures, and list of algorithms together to eliminate the two gaps in between them. How do I go about this?

I'm having trouble running Lualatex in WSL on Windows 10. The same latex file runs smoothly on Linux with Lualatex (both from Texlive 2023). I'm attaching an error message. Thanks!
