We shall find that it is sometimes convenient to subdivide a matrix into rectangular blocks of elements. This leads us to consider so-called partitioned, or block, matrices.
A matrix can be subdivided or partitioned into smaller matrices by inserting horizontal and vertical rules between selected rows and columns.
A partitioning as in Theorem 1.9.4 is called a conformable partition of A and B.
...provided the sizes of the submatrices of A and B are such that the indicated operations can be performed.
