[Numpy-discussion] correlation in fourier domain

I would like to perform 2d correlations between a large matrix A and a bunch
of small matrices B1...Bn. Is there anything built into numpy to help me do
this efficiently in the fourier domain (i.e. DFT of A -> multiplication with
DFT of B1..Bn)?

Cheers,
Alex
