This zip-file contains two m-files that generate 2D spectral plots of smoothing and differentiation filters.

The files are useful for illustration and educational purposes.

Usage:

[w,A] = ztrans1d(h);
[u,v,A] = ztrans2d(h);
u,v,w = 1d and 2d frequencies up the folding frequency. A = amplitude density.
h = 1D and 2D filter coeffecients.
