Optimize legend command?

Hi, I am struggling with LaTeX in legend, so far I wrote legend like:

legendStrings = string(n);
l = legend(legendStrings);
set(l,'interpreter','latex','string','$x^$'+string(n))

I want legend as and s on, but when I didn't write anything after ^ in string argument, MATLAB show me error.

Note:

n is an array of number and I'm plotting ananoymous function using flot withour loop.

Please optimize these lines and guide me how to display correctly.

Thanks

For example,

plot((0:4).^2);
s=string(2);
legend("$x^"+s+"$", 'interpreter','latex')
