plotifl

Plot normalized instantaneous frequency laws

Calling Sequence

plotifl(T, IFLAWS)
plotifl(T, IFLAWS, SIGNAL)

Parameters

T :

a real vector of size M: the time instants,

IFLAWS :

an M by P real matrix with values in [-0.5 0.5]: each column corresponds to the instantaneous frequency law of a signal.

SIGNAL :

a real or complex vector of size M: if given a subwindow is drawn with plot(T,real(SIGNAL))

Description

plotifl plot the normalized instantaneous frequency laws of each signal component.

Examples

N = 140; t = (0:N-1)'; 
[x1,if1] = fmlin(N,0.05,0.3);
[x2,if2] = fmsin(70,0.35,0.45,60);
x1(35+(1:70)) = x1(35+(1:70))+2*x2;
if2 = [zeros(35,1)*%nan ; if2 ; zeros(N-70-35,1)*%nan];
plotifl(t,[if1 if2],x1);
