This paper deals with Vandermonde matrices on Chebyshev points, hereafter denoted by V. We present simple formulas for the determinant of I" and the Frobenius norm of both V and V -~, and derive an algorithm for solving the linear systems l/'p =f and VTq = g. Numerical experiments to asses the stabi
