Inverse Short time Fourier transform.
[X,T]=tfristft(tfr,T,H) [X,T]=tfristft(tfr,T,H,TRACE)
signal.
time instant(s) (default : 1:length(X)).
frequency smoothing window, H being normalized so as to be of unit energy. (default : Hamming(N/4)).
if nonzero, the progression of the algorithm is shown (default : 0).
time-frequency decomposition (complex values). The frequency axis is graduated from -0.5 to 0.5.
tfristft computes the inverse short-time Fourier transform of a discrete-time signal X. This function may be used for time-frequency synthesis of signals.
