Inverse FFT
Description
Matlab/Octave-compatible inverse FFT.
Usage
ifft(x)
Arguments
x
the input array.
Details
It uses fft from the stats package as follows:
fft(x, inverse = TRUE)/length(x)
Note that it does not attempt to make the results real.
Value
The inverse FFT of the input, the same length as x.
