This matlab code is faster in part than your Python equivalent:
| > > z=math.log(m)
because of the repeated lookup of log in the math module.
| > > import math
from math import log
Also make that the top line of the function so 'log' is a local variable.
Then delete 'math.' everywhere.
That said, such artificial benchmarks do not strike me as terribly useful.
More useful, for instance, for appropriate applications, might be doing a
fourier transform on a 2**20 length vector with both matlab and numpy/scipy
