Hey,
Can someone explain this to me?
In [3]: import scipy as S
In [5]: import scipy.signal as SS
In [6]: from numpy.random import rand
In [7]: up = rand(18000)
In [10]: %timeit N.correlate(up,up,mode='full')
10 loops, best of 3: 829 ms per loop
In [11]: %timeit S.correlate(up,up,mode='full')
10 loops, best of 3: 827 ms per loop
In [12]: %timeit SS.correlate(up,up,mode='full')
10 loops, best of 3: 11.5 s per loop
Is this a configuration problem? If not, why does
scipy.signal.correlate even exist?
Thanks,
Ryan
