File Information
Description

!! OBSOLETE !!
Its functionality is now implemented in my function PERMN, available on the File Exchange
permnsub - subset of all permutations with repetition
    M = permnsub(V,N,IX) returns a subset of all permutations, with
    repetition, of N elements, taken from the elements in vector V. M has
    the size numel(IX)-by-N. V can be an array of numbers, cells or strings,
    and M will be of the same type as V.
 
   Use PERMN instead

This is an excellent implementation of a very efficient method. Together with the exhaustive documentation this submission is useful, usable and valuable for the productive work and education. Thanks, Jos!

A tiny simplification: You do not need B(:)', because B is a row vector already.
