Finding ifft for a variable function
显示 更早的评论
Hello
I want to find an ifft for (1+alpha*exp(-j*w*D)) where alpha and D are constants,w should be the frequency variable,
Ifft can't evaluate a function containing a variable though.. Is there anyway this could work?

Why don't you just evaluate the function, as usual, at many sample points and take the ifft of that?

Or if you have the Symbolic Toolbox, you can use ifourier to obtain the inverse Fourier transform symbolically.
