The matlab conv function doesn't provide a way to perform column-wise/row-wise convolution of matrices. Using a loop can be time-consuming. This new function performs this kind of convolution using only matrix operations and fft/ifft. The key to this implementation is the proper zero padding of input matrices. The zip file contains 2 .m files, the function and a demo.This function computes C = fastConv(A,B,dim), where the i-th column/row of C is the convolution of the i-th column/row of A and the i-th cloumn/row of B.

Requirements: No special requirements
