Math::DCT - 1D and NxN 2D Fast Discreet Cosine Transforms (DCT-II)
An unscaled DCT-II implementation for 1D and NxN 2D matrices implemented in XS. For array sizes which are a power of 2 a fast - *O(n logn)* for 1D, *O(n² logn)* for 2D - algorithm (FCT) described by Lee is used with some tweaks. In addition, an unsca...
