COMBN 4.2

COMBN - all combinations of elements M = COMBN(V,N) returns all combinations of N elements of the elements in vector V. M has the size (length(V).^N)-by-N. [M,I] = COMBN(V,N) also returns the index matrix I so that M = V(I). V can be an array of numbers, cells or strings. Example: M = COMBN([0 1],3) returns the 8-by-3 matrix: 0 0 0 0 0 1 0 1 0 0 1 1 ... 1 1 1 All elements in V are regarded as unique, so M = COMBN([2 2],3) returns a 8-by-3 matrix with all elements equal to 2. NB Matrix sizes increases exponentially at rate (n^N)*N. See also PERMS, NCHOOSEK and ALLCOMB, PERMPOS here on the FEX
