Matlab function for discrete Walsh function generation.
y = walshGenerator(N,K)
This function determine the Discrete Walsh function number N of order 2^K
using a recursive algorithm for lower memory requirements. N is a natural
number that ranges from 0 to 2^K-1, being N=0 the Walsh function without
zero crossings and N = 2^K-1 the Walsh function with the maximum
zero crossings (sequency order). This algorithm was been applied according to the
reference:
