Selecting all combinations of points

Hi there,

I have a set of points and I would like to generate a code that selects all the possible combinations (the order doesn't matter) of them.

For example, if I have a matrix with the coordinates of the points A, B, C I want to write other matrices with the coordinates extracted from the sets {}, {A}, {B}, {C}, {A,B}, {A,C}, {B,C}, {A,B,C}.

Thank you in advance for your help :)

Have a look at the nextmultichose at the file exchange: next-combination-permutations, and combinator.
