Align LaTeX math text in matplotlib text box

阅读更多关于 Align LaTeX math text in matplotlib text box

问题 I'm trying to generate a text box with lines of LaTeX code correctly aligned in a matplotlib frame. I tried using the format alignment method (ie: {:<11} ) but it does not seem to work on math mode. Here's the output I get: where the = symbols should all be aligned to the right (see MWE below). How can I produce such a text box with the = signs correctly aligned? MWE : (Never mind the weird figure proportions and text box placing, this is part of a much larger code which I cropped to generate

Centering text in emacs window

阅读更多关于 Centering text in emacs window

问题 Inside just one lonely emacs frame I switch frequently between editting 70-column text files (LaTeX) and 120-column programs (.h/.cpp files). I'd like to continue to use just one emacs frame, without resizing it or creating additional frames. Here is the problem. The width of my window is about right for editting the 120-column programs, but during the extended text editting sessions, the 70 columns appear on the left side of the window. At the end of the day in front of a laptop, my neck

Matplotlib: Change math font size and then go back to default

阅读更多关于 Matplotlib: Change math font size and then go back to default

问题 I've learned from this question Matplotlib: Change math font size how to change the default size of math text in matplotlib . What I do is: from matplotlib import rcParams rcParams['mathtext.default'] = 'regular' which effectively makes the LaTeX font the same size as the regular font. What I don't know is how to reset this back to the default behaviour , ie: the LaTeX font looking a bit smaller than the regular font. I need this because I want the LaTeX font to look the same size as the

Emacs - how do I automatically enter minor modes when I enter a major mode?

阅读更多关于 Emacs - how do I automatically enter minor modes when I enter a major mode?

问题 I'm kind of a newb when it comes to emacs. I know about the .emacs file but have very little idea as to do anything more advanced than elementary stuff. Whenever I enter latex-mode, I'd also like to automatically turn on flyspell-mode, reftex-mode, auto-fill-mode, and also set fill-column to 120. How do I edit my .emacs file to do this? Thanks! 回答1: (add-hook 'latex-mode-hook (function (lambda () (flymake-mode) (reftex-mode) (auto-fill-mode) (setq fill-column 120)))) for example should work.

How do you change the code example font size in LaTeX PDF output with sphinx?

阅读更多关于 How do you change the code example font size in LaTeX PDF output with sphinx?

问题 I find the default code example font in the PDF generated by sphinx to be far too large. I've tried getting my hands dirty in the generated .tex file inserting font size commands like \tiny above the code blocks, but it just makes the line above the code block tiny, not the code block itself. I'm not sure what else to do - I'm an absolute beginner with LaTeX. 回答1: I worked it out. Pygments uses a \begin{Verbatim} block to denote code snippets, which uses the fancyvrb package. The

Replace a character with a string in LaTeX

阅读更多关于 Replace a character with a string in LaTeX

问题 I'm looking for a way to do a substring replace on a string in LaTeX. What I'd like to do is build a command that I can call like this: \replace{File,New} and that would generate something like \textbf{File}$\rightarrow$\textbf{New} This is a simple example, but I'd like to be able to put formatting/structure in a single command rather than everywhere in the document. I know that I could build several commands that take increasing numbers of parameters, but I'm hoping that there is an easier
