Sequence: the data sequence to be transformed
Inverse: if true, the inverse Fourier transform is calculated, defaults to false
Separate: if true, the real and imaginary parts are given separately, defaults to false
This array function returns the Fourier or inverse Fourier transform of the given data sequence.
The output consists of one column of complex numbers if Separate is false and of two columns of real numbers if Separate is true.
If Separate is true the first output column contains the real parts and the second column the imaginary parts.
If Sequence is neither an n by 1 nor 1 by n array, this function returns #VALUE!
