The narray documentation is a bit thin, so I'm asking here. I do want to do a convolution. Map a two dimensional kernel onto a two dimensional image. I thought the 

FFTW.convol(a, b)

function of narray would do this. But I see that it requests to narrays of the same size? So I this can't be convolution. What is it, and where can I find a convolution function?

Regards,

Brian
