Question 4 [35 marks in totalj An n x n matrix A is called a stochastic matrix if it! satisfies two conditions: (i) all entries of A are non-negative; and (ii) the sum of entries in each column is one. If the (,) entry of A is denoted by any for ij € {1, 2,...,n}, then A is a stochastic matrix when alij 20 for all i and j and I j = 1 for all j. These matrices are...

a. Let B be an n x n Orthogonal matrix, that is B^-1 = B^T, and let A be an n x n skew-symmetric matrix. Simplify A(A^2(BA)^-1)^T b. Let A be a square matrix such that A^3 = 0. A is then called a nilpotent matrix. Define another matrix B by the expression B = I - A; Show that B is invertible and that its inverse is I + A + A^2 c. Let B = (-2,0,0 ; 0,0,0...

Throughout this question, fix A as an n×n matrix. If f(x) is a polynomial, then f(A) is the expression formed by replacing every x in f(x) with A and inserting the n×n identity matrix I to its constant term. For example, if f(x) = x2 −2x+5 (whose degree is 2), then f(A) = A2 −2A+5I; if f(x) = −x3 +2 (whose degree is 3), then f(A) = −A3 + 2I. (a) Using induction of the degree of the polynomial f(x),...
