I tried:

title('\nabla');

Which produces no errors or warnings on the terminal, but the title in the plot on my mac is just a little question mark in a black box: � You can do a little better by switching to the latex interpreter, which unfortunately uses that smelly latex font

title('$\nabla$','interpreter','latex');
