adtFFT

adtFFT(
l_list
)
=> l_result / nil

Calculates the fast Fourier transform (FFT) of the specified list.

l_list

List of values for which you want to generate FFT.

l_result	List containing FFT results.
`nil`	FFT cannot be calculated because of an error.

The following example calculates FFT for the specified values.

adtFFT(list(3 9 2 5 1))

=> (complex(20, 0) complex(0.427051, -5.8451) complex(-2.92705, -7.55545) complex(-2.92705, 7.55545) complex(0.427051, 5.8451))
