MATLAB: How to use ‘&’ between two different matrix

Question

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 ?

Answer 1

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'
