Description

Internal function, generally not called by users.

Usage

comb(m, n)

Arguments

m	an integer, corresponding to the number of zeros. It must be greater or equal to zero.
n	an integer, corresponding to the number of ones. It must be greater or equal to zero.

Details

comb builds the matrix with all combinations of m zeros and n ones. The output matrix will hence have as number of columns nc=m+n and as number of rows nr = (m + n)! / (m!n!), which is the number of all the possible combinations. Each row will contain one of the nr possible combinations of m zeros and n ones.
