Comparison of Pseudospectral and Spectral Approximation
The accuracy of pseudospectral (collocation) approximation is compared to spectral (Galerkin) approximation in some simple model problems. It is found that both approximations give similar errors, despite the inclusion of aliasing terms in pseudospectral approximation.
