TeX markup ignored by Matlab?

I'm trying to format a prompt text using the TeX markup. This always worked with my old Matlab version (r2016a) but recently i updated to r2018a. Since then any time i try a modifier or a character sequence, it gets printed as is: for example, \pi is printed as "\pi" with the backslash included. Same goes with modifiers like ^{} and _{}. Even my old codes, which used to work, don't anymore. Any ideas?

Try adding the parameters 'interpreter', 'tex' for commands like title, xlabel ... etc. MATLAB command line however doesn't support tex/LaTex Markup or greek characters according to Mathworks support because of the character set it is using.

Please use this as plot lables

clc;

clear all;

x = 1:100

y = rand(1,100)

plot(x,y)

xlabel({'\pi'},'interpreter','tex')

ylabel({'{\pi_{j}^{k}}'},'interpreter','tex')
