Hello!
I have a function f(OM,T) which depends on two variable: frequency and time; and I now that this function is the Verse Fast Fourier transform of another function g(T). How can I get the second function g(T)?
THANKS

Hi!
I assume that you meant to say 'f' is the inverse fourier transform of the function 'g'.
If that is the case, finding the FFT of 'f' will give you 'g'.
The following doc link will point you towards how to calculate FFT in MATLAB:

Hope this helps!

Yes, my keyboard always changes my sentences in English haha.
My problem is that I have a handle function instead of a vector, can I use fft command with it? Because I've seen in some articles something like this:
f=@(OM) F(OM);
OM=[0:0.01:100];
g=fft(f(OM))
But what I get with that is another vector instead a time-dependant function.
Thankyou for the answer!
