How to make an subscript in this specific manner?

I am trying to print a axis label using the following code to make it italicized

ylabel('$u_max$','interpreter','latex','FontSize',14);

I wanr the "max" to all be a subscript to "u" but as of right now only the "m" is a subscript and the rest of the word is normal alongside the "u". How would I make the whole "max" a subscript in the way I have coded it?

Put the max in braces:

ylabel('$u_{max}$','interpreter','latex','FontSize',14);
