Write your own matlab code to perform matrix multiplication. Recall that to multiply two matrices, the inner dimensions must be the same. Write this as a function with input arguments the matrices to be multiplied and output argument the resultant matrix, use "assert" statement(s) to check that the input arguments are valid and print an error message if they are not. Test with A=[1,2,3;4,5,6] and B=[7,8;9,10;11,12] showing results for: (a) A*B, (b) B*A, and (c) A*A.
(c): Suppose we have the following matrices. Which pairs of matrices can be validly multiplied together? For these pairs perform the multiplication. -2] A = 61-3 1-2 4 6 ,B = -8] 4 ,C = [1 4 2 5 3] 1,D = lo 6

Question 4 [12 marks] Some applications of mathematics require the use of very large matrices (several thousand rows for example) and this in turn directs attention to efficient ways to manipulate them. This question focuses on the efficiency of matrix multiplication, counting the number of numerical arithmetic operations (addition, subtraction and multiplication) involved. We start with very simplest case of 2x2 matrices. (a) The standard way of multiplying 2x2 matrices uses 8 multiplications and 4 additions. List the 8 products...
READ CAREFULLY AND CODE IN C++ Dynamic Programming: Matrix Chain Multiplication Description In this assignment you are asked to implement a dynamic programming algorithm: matrix chain multiplication (chapter 15.2), where the goal is to find the most computationally efficient matrix order when multiplying an arbitrary number of matrices in a row. You can assume that the entire input will be given as integers that can be stored using the standard C++ int type and that matrix sizes will be at...
