This paper analyzes the factorization of the inverse of a Cauchy-Vande
rmonde matrix as a product of bidiagonal matrices. Factorizations of C
auchy-Vandermonde matrices are also considered. The results are applie
d to derive a fast algorithm for solving linear systems whose coeffici
ent matrices are Cauchy-Vandermonde matrices. (C) 1998 Elsevier Scienc
