r24486 - in /branches/frame_order_cleanup/test_suite/shared_data/frame_order/timings: numpy_vs_math.log numpy_vs_math.py -- July 09, 2014 - 10:59

Author: bugman
Date: Wed Jul  9 10:59:03 2014
New Revision: 24486

URL: http://svn.gna.org/viewcvs/relax?rev=24486&view=rev
Log:
Added a timeit script and log file showing how numpy.cos() is 10 times slower 
than math.cos().

This is for single floats.
