For example
aa =
1 2 3
4 5 6
bb =
1 2
3 4
5 6
And I wanna create cc = aa & bb; But there's some problem they said ..
What does it means ? And how can i fix it ?

What would you like the result to be? Do you want the result to be 2 x 3 like aa ? 3 x 2 like bb ? 2 x 2 because that is what they have in common? 3 x 3 by extending to the limits of both?

The dimensions of aa and bb are different. aa is 2X3 and bb is 3x2.. you have to transpose any of the matrix.
Eg:
cc = aa' & bb
or
cc = aa & bb'
