The Inverse of a Matrix
... To see this, note that if A is of order m n and B is order of n m (where m n), the products AB and BA are of different orders and so cannot be equal to each other. Not all square matrices have inverses. If, however, a matrix does have an inverse, that inverse is unique. Example 2 shows how to ...
