how to add a subscript in colour map labels

How to add a subscript to a text(Uo) in matlab 2020a. Please help me to write a subscript to colour map label.

h.Label.String = 'ωc/U_{0}';% not the right way

This code seems to work fine. I am usin R2020a. Can you show what is the output on your system?

you are correct ameer. It only works without LaTex interpreter. Kindly let me know if you know the solution to work with LaTex interpreter.

The interpreter in app designer only works for figure objects (title, labels, text, legend). See this post for possible workarounds for other components.

Here is an official response from Mathworks.

Thanks. I do not the reason why subcrcript is not working with LaTex interpreter. I found out that, it is a limtation in the Matlab. Please let me know the solution.

 h.Label.Interpreter = 'latex';
 h.Label.String = 'ωcU_{0}';

I think the issue here is you have a greek symbol already in your string (omega). This appears to be messing up the interpreter. You have two options. To subscript in a colorbar label, you don't need to specify an interpreter. Try doing just this:

h.Label.String = 'ωcU_{0}'; 

If instead you want to use the latex interpreter, you have to provide valid LaTeX code enclosed in "$":

h.Label.Interpreter = 'latex';
h.Label.String = '$\omega c/U_{0}$';

Thanks, it worked for me.
