rceps() - Signal Processing

The real cepstrum is the inverse Fourier
transform of the real logarithm of the magnitude of the Fourier transform
of a sequence.Note  

rceps only works on real data.rceps(x) returns the real cepstrum
of the real sequence x. The real cepstrum is a
real-valued function.[y,ym] = rceps(x) returns
both the real cepstrum y and a minimum phase reconstructed
version ym of the input sequence.


rceps(x)[y,ym] = rceps(x)


y = real(ifft(log(abs(fft(x)))));
