numpy.ma.convolve

ma.convolve(a, v, mode='full', propagate_mask=True)

Returns the discrete, linear convolution of two one-dimensional sequences.

Parameters:

a, varray_like

Input sequences.

mode{『valid』, 『same』, 『full』}, optional

Refer to the np.convolve docstring.

propagate_maskbool

If True, then if any masked element is included in the sum for a result element, then the result is masked. If False, then the result element is only masked if no non-masked cells contribute towards it

Returns:

outMaskedArray

Discrete, linear convolution of a and v.
