Toeplitz matrices

Toeplitz matrices

A Toeplitz matrix is an n × n matrix A = (aij) such that aij = ai-1, j-1 for i = 2, 3,..., n and j = 2,3,..., n.

a. Is the sum of two Toeplitz matrices necessarily Toeplitz? What about the product?

b. Describe how to represent a Toeplitz matrix so that two n × n Toeplitz matrices can be added in O(n) time.

c. Give an O(n lg n)-time algorithm for multiplying an n × n Toeplitz matrix by a vector of length n. Use your representation from part (b).

d. Give an efficient algorithm for multiplying two n × n Toeplitz matrices. Analyze its running time.
