The function implement the 2D dyadic(Paley) ordered fast in-place Walsh-Hadamard transform, which can be used in signal processing, pattern recognition and Genetic alogorithms. This algorithm uses a Cooley-Tukey type signal flow graph and is implemented in N log2 Nadditions and subtractions. Data sequence length must be an integer power of 2. The inverse transform is the same as the forward transform except for the multiplication factor N x N.

Requirements: No special requirements
Platforms: Matlab
Keyword: Algorithm Cooleytukey Factor Forward Graph Implement Implemented Inplace Integer Inverse Length Multiplication Nadditions Ordered Power Sequence Subtractions Transform Walshhadamard
