MAT = NPERMUTEK(N,K) returns all possible permutations of the elements taken from vector N of length K. This type of sampling is an ordered sample with replacement.
This is also known as the permutations with repetition.
MAT has size (length(N)^K)-by-K, where K must be a scalar.

[MAT, IDX] = NPERMUTEK(N,K) also returns IDX such that MAT = N(IDX).

If N is of class single, MAT and IDX will be also.

Please email me about bugs in the code.
Thanks
