Re[]: real value array
Im[]: imaginary value array
nTotal: total number of complex values
nPass: number of elements involved in this pass of transform
nSpan: nspan/nPass = number of bytes to increment pointer
in Re[] and Im[]
isign: exponent: +1 = forward -1 = reverse
scaling: normalizing constant by which the final result is *divided*
scaling == -1, normalize by total dimension of the transform
scaling < -1, normalize by the square-root of the total dimension
