Please describe the purpose of the new feature or describe the problem to solve.
I would be great to have support for ND convolution of sparse arrays. Basically an implementation of scipy.signal.convolve, with support for sparse arrays.
Suggest a solution if possible.
I have played around a bit with implementing a convolution via sparse matrix multiplication:

But performance wise this is really bad:
Also boundary handling becomes really complex. And I am sure the experts have much better ideas on how to implement this.
If you have tried alternatives, please describe them below.
