plotifl

Plot normalized instantaneous frequency laws.

Calling Sequence

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

Parameters

T :

time instants,

IFLAWS :

(M,P)-matrix where each column corresponds to the instantaneous frequency law of an (M,1)-signal, These P signals do not need to be present at the same time instants. The values of IFLAWS must be between -0.5 and 0.5.

SIGNAL :

if the signal is precised, display it also

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];
figure(1); clf; plotifl(t,[if1 if2]);
figure(2); clf; plotifl(t,[if1 if2],x1);
