Final answer:

To compute AB, perform matrix multiplication between the given matrices A and B.

Step-by-step explanation:

To compute AB, we need to perform matrix multiplication. Given:

A = [0 3 0 1 0 1 0 2 0],

B = [4 9 8 4 -3 -5 3 2 3],

we can compute AB as follows:

AB = [0*4 + 3*4 + 0*3, 0*9 + 3*4 + 0*-5, 0*8 + 3*3 + 0*3,

1*4 + 0*4 + 1*3, 1*9 + 0*4 + 1*-5, 1*8 + 0*3 + 1*3,

0*4 + 1*4 + 0*3, 0*9 + 1*4 + 0*-5, 0*8 + 1*3 + 0*3]

Simplifying the multiplication, we get:

AB = [12, 9, 9,

7, 4, 11,

4, 1, 3]
