I've observed errors when rendering math in matplotlib 2.0.2, when using the default mathtext as opposed to the LaTeX math rendering engine. It seems that some glyphs (in my case the minus and the multiplication sign) is not recognized by mathtext. What makes it really weird is that the error only occurs when these particular glyphs appear in tick labels. When I deliberately type some mathy expression into e.g. the figure title, it works fine. Consider the below example and the resultant image: import matplotlib import matplotlib.pyplot as plt # Customize matplotlib matplotlib.rcParams.update(

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! (add-hook 'latex-mode-hook (function (lambda () (flymake-mode) (reftex-mode) (auto-fill-mode) (setq fill-column 120)))) for example should work. You can set a so-called hook to a major mode. Have a look at this page of the manual for some examples. 来源：

I write documentation in markdown using ViM and I also put math using the latex $$ symbol (I compile using pandoc). The thing is that ViM syntax wouldn't ignore the underscores _ inside the dollar symbols and it is pretty annoying. For instance if I write this: $$ a_1 = 0 $$ Then Vim will highlight all the following text as italics due to to the underscore used. How can I change that? Also it would be nice if I could highlight what's inside $ with a different format. I have put these lines in my .vimrc. It works for inline math on the same line and block-mode math. " This gets rid of the nasty

Rstudio Version 0.99.441; Windows 7 enterprise; knitr 1.10.5; MiKTex 0.4.5 r.1280 (2.9 64-bit) I have a an error on my office computer when trying to knit PDF's in Rstudio, there are no problems knitting to HTML or word. The problem may be related to updates because knitting used to work fine and my home computer can knit to pdf without issue, however I took my computer home to update and the problem is still there. My error message was as follows "pandoc.exe: Error producing PDF from TeX source Error: pandoc document conversion failed with error 43" I created a new file using the template

In general how to debug and solve key bindings overlapping? I had this problem.. Recently I add vim-latex plugin to my vim dir. After that I noticed that my ctrl-j bind is overlapped by vim-latex/plugin/imaps.vim and lost a lot of time until solved that. By the way: there is a bug in imaps.vim i think, because there is written " map only if there is no mapping already" and my example shows opposite. You can get fine-grained info from the :map command: To show only mappings relevant to a particular key (in this case ctrl-J): :map <c-j> or, better, to show mappings for particular key as well as

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 way. Edit for clarification I'm looking for an equivalent of string.replace(",", "$\rightarrow$)
