8- Using the DP approach and the Chain Matrix Multiplication algorithm you have seen in the class, build the CMM tables and find the multiplication sequence that minimizes the number of operations. [3 points] A1 = 10 \times 100 A2 = 100 \times 20 A3 = 20 \times 5 A4 = 5 \times 80

Step 1
The table will have dimensions n x n, where n is the number of matrices to be multiplied. In this case, we have 4 matrices (A1, A2, A3, A4), so our table will be 4 x 4. The table will store the minimum number of operations required to multiply each subsequence Show more…

Using Optimal Parenthesization, find an optimal parenthesization for the chained product of five matrices with dimensions 6x7, 7x8, 8x3, 3x10, 10x6.
Let I be the 4x4 identity matrix (ones on the main diagonal and 0's everywhere else.) Let J be the 4x4 matrix with 1 in each place. Let A = [ 1 0 1 0 ; 0 1 0 1 ; 1 0 1 0 ; 0 1 0 1 ] Express the following matrix as a linear combinations of I, J, and A. [ 3 1 3 5 ; 5 3 1 3 ; 3 5 3 1 ; 1 3 5 3 ]
