Let & the n x n matrix that has ones on its anti-diagonal and zeros elsewhere (aij = 1 if i+j = n + 1, otherwise 0). (a) : What is the entry (i, j) of EAE? (b) A matrix A is said to be persymmetric if EAE AT. Is a Toeplitz matrix persymmetric? [Hint: a persymmetric A is one that is symmetric about its antidiagonal.] (c) : Find an example of a small matrix that is persymmetric but not Toeplitz. (d): Consider a matrix A of the following form A 1 = (-&T C). : Assuming that C is persymmetric, show that A is persymmetric. Assuming that C is Toeplitz is A Toeplitz? [prove if true, find a counter example if false.] Let & the n x n matrix that has ones on its anti-diagonal and zeros elsewhere (aij = 1 if i+j = n + 1, otherwise 0).
