CHOOSRNK All choices of K elements taken from 1:N with replacement. [X]=(N,K) The output X is a matrix of size ((N+K-1)!/(K!*(N-1)!),K) where each row contains a choice of K elements taken from 1:N with duplications allowed. The rows of X are in lexically sorted order. To choose from the elements of an arbitrary vector V use V(CHOOSRNK(LENGTH(V),K)).
