Hi there,
I want to show in my output (not in my plots) the handwritten format of my expression. I have the symbolic toolbox.
% No problem in plots, simple example
x=linspace(0*deg,360*deg,360); % deg is constant in my installation
f='sqrt(abs(sin(x.^2)))'; ff = eval(f);
p=plot(x,ff);
title(['Title ' '$' latex(str2sym(f)) '$'] , 'Interpreter', 'latex');
Now suppose I don't need a plot of any kind and I want to check if I made a mistake in a long expression or equation.
I'd like to show the hand written format of my expression
Refering to the little code over
If I type ['$' latex(str2sym(f)) '$']
I will get the Latex representation ans = '$\sqrt{\left|\sin\left(x^2\right)\right|}$'
Now I want to do this something like this
disp(['$' latex(str2sym(f)) '$'] , 'Interpreter', 'latex');
and get
Can I do something like this ? Not with disp(...) for sure !

No.
Assume there is no plot, I cannot use title alone.
I forgot to say that I use the Live Editor and common sense tells me that the output must be a text region
So I rewrite the code, it should be as simple as that with no plot !
clf
x=linspace(0*deg,360*deg,300);
f='sqrt(abs(sin(x.^2)))'; ff = eval(f);
SomeCallingFunctionOrSomething(['$' latex(str2sym(f)) '$'] , 'Interpreter', 'latex');
And it should add or modify a text region with
Of course I can do it manually just take \sqrt{\left|\sin\left(x^2\right)\right|} then Insert LaTex Equation and Paste and it will add my text region with the correct output but I want to do it programmatically.

sympref('TypesetOutput','default')
f = str2sym('sqrt(abs(sin(x.^2)))') % gives the desired result in livescript

PERFECT !
clf
x=linspace(0*deg,360*deg,300);
f='sqrt(abs(sin(x.^2)))'; ff = eval(f);
disp(str2sym(f));
So simple, sometimes we're almost ashamed to have asked such a simple question but I am sure some people will add it to check mistakes in there big equations.

You don’t have to be ashamed of asking a question. By the way please don’t use eval() it’s completely unnecessary.
