Difference between rceps and cceps in MATLAB I'm trying to construct a cepstrum using MATLAB built in function but I don't get the difference between MATLAB's functions rceps and cceps.
Can anyone explain to me the difference between rceps and cceps?
RTFM? rceps says:

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


while cecps says:

h = fft(x);
logh = log(abs(h)) + sqrt(-1)*rcunwrap(angle(h));
y = real(ifft(logh));
