  author={Michael Stewart and Paul Van Dooren},
This paper provides an error analysis of the generalized Schur algorithm of Kailath and Chun|a class of algorithms which can be used to factorize Toeplitz-like matrices, including block-Toeplitz matrices, and matrices of the form T T T , where T is Toeplitz. The conclusion drawn is that if this algorithm is implemented with hyperbolic transformations in the… CONTINUE READING
