How to calculate FTT with a dimension

Posted 10 years ago
Hallo, 
how can i calculate the FFT with a dimension? Like:
fft(my_list,n) // n = dimension
Thank you very much!

Fourier can compute the FFT of an array of arbitrary dimension.  See it's documentation:

Thanks but i mean , Y = fft(X,n) with a  the n-point DFT, where n is the size of X in the first nonsingleton dimension. ( n = Next power of 2 from length of y)

OK i found it :
f=Fourier[PadRight[my_list,n,0.]]

I see.

A gentle suggestion:  when you post a question, explain it in detail.  From your initial post it was not clear wht you were asking. 

Best,
David
