Chebyshev and Fourier Spectral Methods the book's margins feature step-by-stepCompletely revised text focuses on use of spectral methods to solve boundary value, eigenvalue, and time dependent problems, but also covers Hermite, Laguerre, rational Chebyshev, sinc, and spherical harmonic functions, as well as cardinal functions, linear eigenvalue problems, matrix solving methods, coordinate transformations, methods for unbounded intervals, spherical and cylindrical geometry, and much more. 7 Appendices. Glossary. Bibliography.
