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

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

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)

Fourier can compute the FFT of an array of arbitrary dimension. See it's documentation: http://reference.wolfram.com/mathematica/ref/Fourier.html
