Vandermonde matrices on Chebyshev points Original Research Article

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 V P=ƒ and VTq=g. Numerical experiments to asses the stability of this algorithm are also reported.
