Version Published Release Notes
1.1.0.1

I have updated only the title of this contribution for better public visibility.

1.1.0.0

I have improved dif_fft.m and rec_fft.m by killing some unneeded for loops. I also have included an FFT implementation (both in matlab and mex-coded) found in "Numerische Mathematik kompakt" by Robert Plato.
I have only modified the title of this submission.
