The accuracy in the output of TIC/TOC has been improved for MATLAB 7.0.1(R14SP1) and later versions for the Windows and Linux(glnx86) platforms. The builtin functions TIC and TOC have been rewritten to improve the performance and accuracy on all platforms.
MATLAB 7.0.1(R14SP1) and later versions, now use the CPU cycle counter on Windows and Linux to evaluate the timing results. For example, on a 2.8 GHz, Windows XP (Service Pack 2) machine, TIC/TOC returns an accuracy of 1.117460e-006 sec, in MATLAB 7.0.4 (R14SP2).
