# MATLAB: Unable to interpret LaTeX string “$\mathfrak{K}$”

ylabel mathfrak latex

Hello all,
I am trying to label my y-axis using a LaTeX string containing \mathfrak{K}, but it is not accepted by Matlab. Is there something special to do (like in a LaTeX document where you would put \usepackage{amsfonts} in the preamble)?
Here is what I tried so far: ylabel('$\mathfrak{K}$','Interpreter','Tex') ylabel('$\mathfrak{K}$','Interpreter','LaTex')
None of them worked correcly.
Thank you for your time and help
