PseudoPack

Abstract

PseudoPack is a software library for numerical differentiation by pseudospectral methods. Three different collocation methods are incorporated into the package: Fourier method, Chebyshev method, Legendre method. Special fast algorithms are provided for cases where the function being differentiated has either even or odd symmetry. A filtering algorithm for smoothing both the differentation and the function itself is especially useful for maintaining stability when solving non-linear/non-smooth PDEs.
