Recall that if A is an m times n matrix and B is a p × q matrix, then the product C = AB is defined if and only if n = p. in which case C is an m × q matrix.
a. Write a function M-file that takes as input two matrices A and B, and as output produces the product by rows of the two matrices. For instance, if A is 3 times 4 and B is 4 times 5, the product AB is given by the matrix
C = [A(1, :)*B; A(2, :)*B; A(3, :)*B]
The function file should work for any dimension of A and B and it should perform a check to see if the dimensions match. Call the file rowproduct. m. Generate two random matrices A and B and compare the output of your function file with the product A*B.
Include in your lab report the function M-file and the output obtained by running it.

Publish using a MatLab function for the following:
If a matrix A has dimension n×n and has n linearly independent
eigenvectors, it is diagonalizable.This means there exists a matrix
P such that P^(−1)AP=D, where D is a diagonal matrix whose diagonal
entries are made up of the eigenvalues of A. P is constructed by
taking the eigenvectors of A and using them as the columns of P.

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.

In this exercise, you will work with a QR factorization of an mxn matrix. We will proceed in the way that is chosen by MATLAB, which is different from the textbook presentation. An mxn matrix A can be presented as a product of a unitary (or orthogonal) mxm matrix Q and an upper-triangular m × n matrix R, that is, A = Q * R . Theory: a square mxm matrix Q is called unitary (or orthogona) if -,or equivalently,...
