Description
Performs n-point Fast Fourier Transform (FFT)
analoguous to MATLAB's fft(x,n).
Usage
1
Arguments
x
vector or array on which to perform the FFT.
n
Desired length of the FFT. Defaults to length of x.
Details
If x is a vector, fftn either truncates
x or pads it with trailing zeros to make its
length exactly n. For array, each column is adjusted
in this way.
After padding or truncating, the routine calls fft on
the altered vector or array.
Value
Return value is the same as fft.
