CombVec Generate all possible combinations of input vectors.
CombVec(A1,A2,...) takes any number of inputs,
A1 - Matrix of N1 (column) vectors.
A2 - Matrix of N2 (column) vectors.
...
and returns a matrix of (N1*N2*...) column vectors, where the columns
consist of all possibilities of A2 vectors, appended to
A1 vectors, etc.
Example
a1 = [1 2];
a2 = [3 4; 3 4];
a3 =
CombVec(a1,a2)
a3 =
1 2 1 2
3 3 4 4
3 3 4 4
