MATLAB: How to include custom latex usepackage in matlab e.g. labels of figure

usepackage of latex

Hi, I want to use a usepackage e.g. \physics of latex in matlab to produce some special symbol in my label, but I did not find a easy wag to include it. I also open tex.m(%matlab\toolbox\matlab\graphics) file, but there is nothing in it. I use matlab2016b in win10, I have installed miktex 2.9 and all of the package. Is there a way to include the usepackage from miktex to matlab? Thanks forward
