Schematic interference diagram of FM signals
plotsid(T, IFLAWS) plotsid(T, IFLAWS, K)
a real vector of size M: the time instants,
an M by P real matrix with values in [-0.5 0.5]: each column corresponds to the instantaneous frequency law of a signal.
a real scalar with possible values -1, 0, 1/2, 2 or %inf: the distribution (default : 2):
K=2: Wigner-Ville
K=1/2: D-Flandrin
K=0: Bertrand (unitary)
K=-1 Unterberger (active)
K=%inf: Margenhau-Hill-Rihaczek
plotsid plots the schematic interference diagram of (analytic) FM signals.
