How can I get mathematical expression output on Matlab app designer in pretty format

How can I get mathematical expression output on Matlab app designer in pretty format. I want d text field to display calculation results as x²instead of x^2

You might need to do text analysis and substitution, such as

regexprep(S, {'\^2', '\^3'}, {char(178), char(179)})

In particular, uitextarea() does not support any Interpreter property at this time.

I am seeing contradictory material on whether text() supports interpreter latex in AppDesigner. The material that says it does work is newer than the material that says it does not work, so it might be the case that it was added in a more recent release.

If you are doing a symbolic calculation, you could experiment with latex() of the symbolic expression, and text() that into place on a graph (not a text area)

What does that mean text analysis do? I tried using latex interpreter to to text d expression to plot, but it keeps saying only character vector and string vector can be accepted

[Walter Roberson]

S = char(YourSymbolicExpression)

Now S is a character vector that you can analyze and modify.

You can also try

L = latex(YourSymbolicExpression) ;
text(x, y, L, 'interpreter', 'latex')

Notice that you do not ask to text YourSymbolicExpression itself.

It's giving me d expression in latex form Something like \sin(x^2) Instead of sin x²

[Walter Roberson]

L = latex(YourSymbolicExpression) ;
text(x, y, ['$' L '$'], 'interpreter', 'latex')

Thanks so much,it works
