P. 57
(a)
(b)
If A and B are partitioned into submatrices, for example,
15.
then can be expressed as
provided the sizes of the submatrices of A and B are such that the indicated operations can be performed. This method of
multiplying partitioned matrices is called block multiplication. In each part, compute the product by block
multiplication. Check your results by multiplying directly.
