I have problem with the GUI in past releases. I usually type out the syntax on the Command Window.

title('$\hat{\theta}_{estim}$', 'interpreter', 'latex')
xlabel('$\sqrt{x}$', 'interpreter', 'latex')

It does not work on mine side, I am editing directly on canvas ... and it's not working

[Peter]

Hmm, funny ... when I applied $\hat{\theta}_{estim}$ on canvas directly for a first time then it is not working

I applied your from cmd line

title('$\hat{\theta}_{estim}$', 'interpreter', 'latex')

then it depicts correctly ...

and afterwards I might applied it directly then it works ....

Thanks for help and suggestions.

[Sam Chak]

I see. I guess it worked because it first needs to initialize the LaTeX interpreter."

[Peter]

always you need to initialize the interpreter from cmd line?

[Sam Chak]

The GUI cannot differentiate between whether the user wants to display $\sqrt{x}$ or .

Nowadays, I write all my code in scripts; however, on rare occasions, I need to demonstrate to some students how to use certain UI-assisted apps to aid in their designs. Nevertheless, you may consider suggesting to the MathWorks team the enhancement of the GUI by adding a LaTeX toggle button.
