[Savannah-users] a simple case of testing instfreq

[cosmoslu]

Hi,

Sorry to bother you.   
I got instfreq.m from tftb-0.2 package and I'm using hhspectrum.m to compute 
the instantaneous frequency after Hilbert transform. I used a very simple case 
here to test the program, but I don't why Matlab just shows error: ('T can not 
be equal to 1 neither to the last element of X')  Would you please help me?  
Thank you.


Here's my simple code:

clear all
h=0.0001;
t=0:h:2;
x=10*sin(2*2*pi*t);
[A,f,tt] = hhspectrum(x,t);
