R. Baltensperger et Jp. Berrut, The errors in calculating the pseudospectral differentiation matrices for Cebysev-Gauss-Lobatto points, COMPUT MATH, 37(1), 1999, pp. 41-48
We discuss here the errors incurred using the standard formula for calculat
ing the pseudospectral differentiation matrices for Cebysev-Gauss-Lobatto p
oints. We propose explanations for these errors and suggest more precise me
thods for calculating the derivatives and their matrices. (C) 1998 Elsevier
