This computes a²·a̅ instead of a·a̅.
What is the source code for residualPowerOf2?
Also is there any performance issues? can I make this faster?
Probably you should use
http://dlang.org/phobos/std_complex.html#.sqAbs instead. Y

You then also don't need the final map to extract the real part.
(This is actually not true, your inverseFFT presumably still returns
complex numbers.)

Hi
My question is more about Maths than D lang,
I am hoping, maybe somebody worked with AutoCorrelation function before.
auto autoCorrelation(R)(R range)
if (isRandomAccessRange!R)
{
auto residual = residualPowerOf2(range.length); // Fin

No idea about the maths behind it are but:
Thanks a lot for your answer anyway. I am hoping even not related
with D directly, this discussions may atract people from other
languages to D while looking for Domain information.
