It works for me as you wrote it (in R2014b). The only possibility that comes to mind is to specify the interpreter. See if this improves things:

ylabel('\surd Drain-Source Current (A)','Interpreter','tex');

I try it but i get the same problem, it seems that there may be a problem with my tex interpreter.

So i tryed to use latex and it works =]:

ylabel('$\sqrt{}$ Drain-Source Current (A)','Interpreter','latex')

Thanks by the way Star Strider, i didnt imagine that label's had tex and latex interpreters!!!

My pleasure!

I thought about 'latex', but without knowing what MATLAB release you have (LaTeX has only been an option for the last few releases if I remember correctly), decided not to suggest it.
