Matrix multiplication Compute the product \( \underline{\underline{A}} \cdot \underline{\underline{B}} \) of the matrices below. Determine the size of the output matrix first. \[ \underline{\underline{A}}=\left[\begin{array}{rrrr} 1 & 0 & -2 & 0 \\ 2 & 1 & 2 & -1 \\ 3 & -1 & 4 & 1 \\ -1 & 0 & 3 & -2 \end{array}\right] \quad \underline{\underline{B}}=\left[\begin{array}{rr} 2 & 1 \\ -5 & 0 \\ -1 & 2 \\ 3 & 2 \end{array}\right] \]
