Explain an example of Block Multiplication.

Expert Solution
Step 1

To Do:
We have to explain an example of Block Multiplication.

Step 2

Let us consider two block matrices:

A=12¦134¦0¦00¦2 and B=123¦1456¦1¦000¦1

Here A=PQ01×2R and B=XY01×3Z

Where P, Q, R, X, Y, and Z are the given blocks, and 01×2 and 01×3 are zero matrices of indicated sited.

Hence,

AB=PXPY+QZ01×3RZ
