3. Matrix multiplication Compute the product $A \cdot B$ of the matrices below. Determine the size of the output matrix first. $A = \begin{bmatrix} 1 & 0 & -2 & 0 \\ 2 & 1 & 2 & -1 \\ 3 & -1 & 4 & 1 \\ -1 & 0 & 3 & -2 \end{bmatrix}$ $B = \begin{bmatrix} 2 & 1 \\ -5 & 0 \\ -1 & 2 \\ 3 & 2 \end{bmatrix}$

Step 1
To do this, we need to consider the number of rows in matrix A and the number of columns in matrix B. Matrix A has 2 rows and 2 columns. Matrix B has 3 rows and 3 columns. Since the number of columns in A is equal to the number of rows in B, the resulting matrix Show more…
