numpy.correlate

numpy.correlate(a, v, mode='valid')

Discrete, linear correlation of two 1-dimensional sequences.

This function is equivalent to

>>> np.convolve(a, v[::-1], mode=mode)

where v[::-1] is the reverse of v.

Parameters:

a, v : array_like

Input sequences.

mode : {‘valid’, ‘same’, ‘full’}, optional

Refer to the convolve docstring. Note that the default is valid, unlike convolve, which uses full.
