This page documents some common problems and pit-falls that can occur both when using matlab2tikz or when you are changing its source code.

• TeX capacity exceeded has its own page.
• Boxplots exported from R2014a and below may fail to compile in LaTeX with a dimension too large error. There is a specific work-around available on the FileExchange in case cleanfigure doesn't cut it.
• Images look blurry when exported to PNG. This is a known feature of many PDF viewers (e.g. see StackOverflow). Some viewers (e.g. Apple Preview) allow to switch this off in the settings.
• pgfplots 1.12 is known to have some incompatibilities with the LuaLaTeX compiler. Those bugs are fixed in pgfplots 1.12.1 (included from TeX Live 2015 onwards).
• pgfplots and the signalflow package are incompatible. A work-around exists that you can load into your LaTeX document:

\usepackage{pgfplots}
\let\OLD=\pgfnodeparttextbox
\usepackage{signalflowdiagram}
\let\pgfnodeparttextbox=\OLD

• Some features in MATLAB/Octave may have changed. More information is on another page of the wiki.
