2. Partitioned matrices A matrix A is a (2 x 2) block matrix if it is represented in the form [ A 1 A2 1 A = | A3 A4 where each of the A; are matrices. Note that the matrix A need not be a square matrix; for instance, A might be (7 x 12) with Aj being (3 x 5), A2 being (3 x 7), A3 being (4 x 5), and A4 being (4 x 7). We can...
matlab Problem 6: The Matlab command 'randn(m,n) produces an m x n matrix of random numbers that are a realization of a white random process with some probability density function. Moreover, the Matlab command 'rand(m,n)' produces an mxn matrix of random numbers between 0 and 1 that are a realization of a white random process with some probability density function. a) Use Matlab to do the following steps: 1) Let u-randn (10000,1); and plot u. 2) Use the command 'mean(u)'...

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,...
