'W' matrix (for filter) cannot be constructed when NPML=[0,0].

Hi,
When I don't want to use PML and make it [0,0], get_W function from filter gives the error 'dimension mismatch' while constructing W matrix as sparce matrix.
I think that problem is on defining i_range and j_range but I couldn't find how to change them properly.
