Given the following matrices A4 3 2 B3 5 8 5 4 5 1 4 6 1 3 5

Given the following matrices:

A=[4 3 2         B=[3 5 8

      5 4 5              1 4 6

      1 3 5]              2 5 6]

Multiply the two matrices (matrix multiplication) and store the result in the variable D. (Note: D = A times B...not B times A)

Multiply matrix D element-by-element with matrix B and store in variable E.

Copy and paste your code below.

Solution

AB=D=[12 15 16

5 16 30

2 15 30]

DB=E=[36 75 128

5 64 180

4 75 180]
