Many of the currently popular 'block algorithms' are scalar algorithms in which the operations have been grouped and reordered into matrix operations. One genuine block algorithm in practical use is block LU factorization, and this has recently been shown by Demmel and Higham to be unstable in gener

This Paper analyzes the factorization of the inverse of a Cauchy-Vandermonde matrix as a product of bidiagonal matrices. Factorizations of Cauchy-Vandermonde matrices are also considered. The results are applied to derive a fast algorithm for solving linear Systems whose coefficient matrices are Cau
