Web1 Dynamic Programming Examples Matrix-Chain Multiplication Problem • Given a chain of n matrices where Ai is of size Pi-1 × Pi • How can we multiply them so that min # of scalar multiplications is performed WebWe don’t need to find the multiplication result but the order of matrices in which they need to be multiplied. Matrix chain multiplication in C++ is an interesting problem. The matrix multiplication is associative, thus we have various ways to multiply. For example-suppose A is a 15 × 20 matrix, B is a 20 × 5 matrix, and C is a 5 × 40 matrix.
