Bounds for Inverses of Triangular Toeplitz Matrices
Kenneth S. Berenhaut, Daniel C. Morton, Preston T. Fletcher · SIAM Journal on Matrix Analysis and Applications · 2005
This short note provides an improvement on a recent result ofVecchio on a norm bound for the inverse of a lower triangular Toeplitz matrix with nonnegative entries. A sharper asymptotic bound is obtained in addition to a version for matrices of finite order. The results are shown to be nearly best possible under the given constraints.
