Description

The function implement the 1D Walash Transform which can be used in signal processing,pattern recognition and Genetic algorithms. The Formula of 1D Walsh Transform is defined as :

%% N-1 q-1
%% ---- --
%% 1 \ | | b[i](m)*b[q-1-i](u)
%% W(u) = --- / f(m)| | (-1) ,u = 0,...,N-1
%% N ---- | |
%% m=0 i=0

%% where for instance ,A[i] is the ith indices of A.
