Optimize legend command?

1 次查看(过去 30 天)
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')
