Matrix Chain Multiplication Hard Accuracy: 59.72% Submissions: 22478 Points: 8 Given a sequence of matrices, find the most efficient way to multiply these matrices together.
Problem 1. Solve the following 2×2 matrix multiplication: See solution. It is a product of matrices of order 2: To solve a matrix product we must multiply the rows of the matrix on the left by the columns of the matrix on the right. Therefore, we first multiply the first row by the first column. To do this, we multiply each element in the ...

Matrix multiplication is associative, so the following equation always holds: Matrix multiplication also has the distributive property, so: The product of matrices is not commutative, that is, the result of multiplying two matrices depends on the order in which they are multiplied: For example, the following matrix multiplication gives a result:
Given a sequence of matrices, find the most efficient way to multiply these matrices together. The efficient way is the one that involves the least number of multiplications. The dimensions of the matrices are given in an array arr[] of size N (such that N = number of matrices + 1) where the i th matrix has the dimensions (arr[i-1] x arr[i]) .
