t = cputime; surf(peaks(40)); e = cputime-t

e =
     0.4667

Tips

Although it is possible to measure performance using the cputime function, it is recommended that you use the tic and toc functions for this purpose exclusively. See Using tic and toc Versus the cputime Function in the MATLAB Programming Fundamentals documentation for more information.
