[Octave-patch-tracker] [patch #9570] [octave forge] (signal) new function cconv: modulo-N circular convolution

[Leonardo]

Follow-up Comment #5, patch #9570 (project octave):

The previous post was indeed using matrix method.

The FOR loop was performing the matrix method... as suggested, now it is using
iFFT and FFT.

The first IF just add zeros for different length vectors.
The second IF fold the vectors into themselves in case the N (modulo) is
smaller than the vector lengths, or add zeros if necessary.
