1. (10 points) Matrix-Chain Multiplication (a) Perform matrix multiplication for the following two matrices. $\begin{bmatrix} 1 & 2 & 3 \\ 0 & 4 & 1 \end{bmatrix} \times \begin{bmatrix} 1 & 2 & 3 \\ 3 & 0 & 1 \\ 5 & 1 & 2 \end{bmatrix}$ (b) Suppose there are two matrices $A_1 A_2$ with dimensions $< p_0 \times p_1 >$ and $< p_1 \times p_2 >$, respectively. How many scalar multiplications are required to perform to find the product of the two matrices? (c) Suppose there is a chain of matrices $A = A_1 A_2... A_n$ with dimensions $< p_0, p_1,..., p_n >$. What are the dimensions for the product matrix A?
