Please answer through MATLAB and show WHOLE script. 1. An n x n matrix is said to be diagonally dominant if , lail for i = 1,...,n ji Basically, if for every row, the absolute value of the entry along the main diagonal is larger than the sum of the absolute values of all other entries on that row. Write a function whose input is a matrix and will determine (true/false) if a matrix is diagonally dominant. Show that your...
9. A diagonal matrix is a square matrix that has only zero value entries on the off-diagonal. Show that the eigenvalues of a diagonal matrix are the values on the diagonal of that matrix.
Please answer the 25,26, and 27 25) A square matrix A = (a ) is called diagonal if all its elements off the main diagonal are zero. That is, aij = 0 if j. (The matrix of Problem 24 is diagonal.) Show that a diagonal matrix is invertible if and only if each of its diagonal components is nonzero. 26.) Let a1i 0 0 0 a22 0 00ann be a diagonal matrix such that each of its diagonal components is...
A magic square is a square of numbers with each row, column, and diagonal of the square adding up to the same sum, called the magic sum. Arrange the numbers,-1,0,1,2,3,4,5,6,and 7 into a magic square. How does the average of these numbers compare with the magic sum?
Suppose that A is a 3 x 3 matrix with constant row sums equal to 4. That is, the sum of the entries in each row of A gives the same value 4. Then the vector of all ones į is an eigenvector corresponding to the eigenvalue X=4 True False The zero vector is always considered to be an eigenvector of a square matrix A. True O False
Question 3: (a) (4 points) Recall that the trace of a square matrix is the sum of all its entries from the main diagonal. Show that the trace is linear, in the sense that, trace(aX + βΥ) trace(X) + β trace(Y). Let V be the space of all m × n matrices. A function <..) : V × V → R is defined as (A, B) trace(ABT), A, B E V. (a) (4 points) Using the properties of the trace,...

The question is attached in following two photos. Please use Matlab if you exactly know how to do it. Thank you. Linorm.m Create a function Linorm which takes one argument, M a square matrix and computes the LI-norm of the matrix. This is a number associated to each square matrix M, denoted lIMll, as follows. For each column of the matrix we add together the absolute values of the entries in that column, and we then take the maximum of...
3. A square matrix is said to be doubly stochastie if istries ae all nonnegative and the entries in each row and each column sum to 1. For any ergodic doubly stochastic matrix, show that all states have the same steady-state probability.
