Hello,

I am looking for a kind of converter which convert from a matlab code

e.^(x./2) * sin(ax)

To symbolic math notation.

Like this website does => http://www.integral-calculator.com/

Does MATLAB have some kind of tools to convert messy parenthesis and functions to more visual friendly notation ?

When my functions gets too complicated, it is difficult to read it and spot the errors in code version like this function at the below.

   int((((x-z-0.5).^2 +(y-w).^2).^(-2)).*(1./(2.*pi.*0.25.^2)).*exp(-(1./(2.*0.25^2)).*(x.^2+ y.^2))./(10.*0.5.^(-4) +((x-z-0.5).^2 +(y-w).^2).^(-2)))

pretty does not do what you want?

help pretty
syms x y z w
pretty(int((((x-z-0.5).^2 +(y-w).^2).^(-2)).*(1./(2.*pi.*0.25.^2)).*exp(-(1./(2.*0.25^2)).*(x.^2+ y.^2))./(10.*0.5.^(-4) +((x-z-0.5).^2 +(y-w).^2).^(-2))))

The pretty function is one option. Writing your symbolic code in the Live Editor directly is another option. A third would be to convert your symbolic expression to LaTeX using the latex function and paste that code into the Live Editor's Equation editor.

syms a x
f = exp(x./2)*sin(a*x);
L = latex(f);
clipboard('copy', L);

Now add a LaTeX Equation to your Live Script (click the triangle next to Equation in the Live Editor tab of the Toolstrip) and paste the LaTeX equation code from the clipboard into the editor.
