Time-Frequency Representations and Local Autocorrelation

timecorr(v, t, f, s, [d]) Returns a matrix containing the samples of a time-dependent autocorrelation function for a signal v, type t, l number of lags, step size s, and an optional scalar or matrix argument d.

timefreq(v, t, f, s, [d]) Returns a matrix containing the bilinear time-frequency representation for a signal v, type t, f number of frequencies, step size s, and an optional scalar or matrix argument d.

Arguments:

When t is "custom", only v, s, and the following argument are required:
