Plot normalized instantaneous frequency laws
plotifl(T, IFLAWS) plotifl(T, IFLAWS, SIGNAL)
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 or complex vector of size M: if given a subwindow is drawn with plot(T,real(SIGNAL))
plotifl plot the normalized instantaneous frequency laws of each signal component.
