all combinations of values in given vectors

[Sebastian H]

Dear MATA users,

Is there a routine to create a matrix containing all possible combinations of values stored in given vectors.

For example:
a = (1\0)
b = (1\0)

should result in c = (1,1\1,0\0,1\0,0)

or
a = (1\0)
b = (1\0)
c = (1\0)

should result in d = (1,1,1\0,1,1\1,0,1\1,1,0\1,0,0\0,1,0\0,0,1\0,0,0)

Best wishes
Sebastian
