Abstract

This paper deals with Vandermonde matrices on Chebyshev points, hereafter denoted by V. We present simple formulas for the determinant of V and the Frobenius norm of both V and V-1, and derive an algorithm for solving the linear systems Vp=f and VTq = g. Numerical experiments to asses the stability of this algorithm are also reported. © 1998 Elsevier Science Inc. All rights reserved.
