MATLAB: How to combine sprintf, fractions, greek characters, and xlabel

Question

What is wrong with this? Each piece prints individually under the x-axis, but combining the three statements is not successful.

xlabel([sprintf('Nondimensional time %c = ',964),'$\frac{t_{fz}}{t_{scale}}$', ...
        sprintf('\n$t_{scale}$ = %.2g s',tscale)],'interpreter','latex');

Answer 1

When you use latex interpreter, you cannot use any character position past 255.

I suggest using \tau
