Calculates the forward discrete cosine transform (DCT) of the Vec.

Pascal
function DCT(const Vec: TVec): TVec; overload;
Description

Writes the result in the calling vector. If Vec.Length is a power of 2, the function uses an efficient algorithm that is significantly faster than the direct computation of DCT. For other values of Vec Length, this function uses the direct formulas.
