Hi,
is it possible to include the "amssymb" package for the latex interpreter. I want to use the \$\square\$ latexcommand in a plot legend. All solutions with modify matlabsystemfiles like tex.m does not work. I use Matlab 2017a.
Thanks for a solution

Unfortunately, somewhere around R2016b or so, MATLAB changed how latex is processed. The text control files that could be edited before are now binary with undocumented format. It is currently not known how to add packages. (Though the pdflatex approach potentially still works; I am not familiar with that.)
