Is it possible to display matrices using MaTeX? I tried:
MaTeX["\\begin{matrix}c\\\\f\\end{matrix}"] but it did not display the matrix.

It works for me
this option setting is not even needed, works without it, but you could try adding it, may be your latex is different.
SetOptions[MaTeX, "Preamble" -> {"\\usepackage{amsmath}"}]; Now
MaTeX["\\begin{pmatrix} 1 & 2 & 3\\\\ a & b & c \\end{pmatrix}", Magnification -> 2] 
MaTeX["\\begin{matrix}c\\\\f\\end{matrix}", Magnification -> 2] 
MaTeX["\\begin{bmatrix} 1 & 2 & 3\\\\ a & b & c \\end{bmatrix}", Magnification -> 2] 
MaTeX["\\begin{Bmatrix} 1 & 2 & 3\\\\ a & b & c \\end{Bmatrix}", Magnification -> 2] 
MaTeX["\\begin{Vmatrix} 1 & 2 & 3\\\\ a & b & c \\end{Vmatrix}", Magnification -> 2] 
MaTeX["\\begin{vmatrix} 1 & 2 & 3\\\\ a & b & c \\end{vmatrix}", Magnification -> 2] 
Also you can do
(data = Table[i + j, {i, 3}, {j, 4}]) // MatrixForm 
MaTeX[TeXForm@data, Magnification -> 2] 
- $\begingroup$ Actually,
\usepackage{amsmath}is already in the default preamble (in"BasePreamble") because the output ofTeXFormsometimes requires it. This is why the setting is not needed. $\endgroup$Szabolcs– Szabolcs2020-04-08 08:26:41 +00:00Commented Apr 8, 2020 at 8:26 - $\begingroup$ @Szabolcs Thanks, this explains why then it worked without needing
amsmathexplicitly added, since these commands come from this package. Yes, one can not do much math without this package, so having it there by default is a good idea. $\endgroup$Nasser– Nasser2020-04-08 08:41:36 +00:00Commented Apr 8, 2020 at 8:41
