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)

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
