QUESTION:
In Exercises, assume that the matrices are partitioned conformably for block multiplication. Compute the products. Suppose A11 is an invertible matrix. Find matrices X and Y such that the product below has the form indicated. Also, compute B22. [Hint: Compute the product on the left, and set it equal to the right side.]
ANSWER:Solution: Step 1: We have to find the formulas for X, Y, and Z in terms of A, B, and C, and justify calculations.
