Latex in plot title with variables

Hi, I'm running Matlab R2014b. Trying to make a nice plot with :

 title([' Slip regulation \lambda for  K_{\sigma} = ',num2str(Ksigma),' K = ', num2str(K),' and \epsilon = ', num2str(theta)]);

Tried even with

 title([' Slip regulation \lambda for  K_{\sigma} = ',num2str(Ksigma),' K = ', num2str(K),' and \epsilon = ', num2str(theta), 'Interpreter','tex' ]);

Still no luck. Would someone help me out ? Thanks in advanced.

Solved it using:

mytitleText = [' Slip regulation \lambda for  K_{\sigma} = ',num2str(Ksigma),' K = ', num2str(K),' and \epsilon = ', num2str(theta)];
title(mytitleText,'Interpreter','tex' );
