Butterworth time-frequency distribution
[TFR,T,F] = Ctfrbud(X) [TFR,T,F] = Ctfrbud(X, T) [TFR,T,F] = Ctfrbud(X, T, N) [TFR,T,F] = Ctfrbud(X, T, N, G) [TFR,T,F] = Ctfrbud(X, T, N, G, H) [TFR,T,F] = Ctfrbud(X, T, N, G, H, SIGMA)
Analyzed signal

number of frequency bins (default : length(X)).
time smoothing window (default : Hamming(N/4)).
frequency smoothing window(default : Hamming(N/4)).
kernel width (default : 1).
time-frequency representation
vector of normalized frequencies.
