Didn't make any tests, you're welcome to test it. But i don't expect
any problems with timing. Multi-threading will only be applied by
Matlab during execution/computation of specific Matrix operations
and mathematical computations, so i'd expect a speedup during
heavy computations, e.g., FFT's, convolutions in Matlab, element-
wise Matrix/vector operations etc. and maybe in a few of our own
M-Files.
Multithreading won't be active during execution of our MEX files,
so their timing should not be affected in any way.
The only areas that could be theoretically affected are routines
that work already in parallel threads and had the option of running
undistracted on a 2nd core, e.g., Quicktime movie playback and
video capture engine. But its unlikely that you perform heavy
computations during the inner trial loop anyway while you are
playing a movie etc.
