Lecture 5 Part 2 Solving Odes In Gnu Octave Pdf Ordinary In [1] we introduced new algorithms to reduce the roundoff error in com puting derivatives of a function by matrix vector multiplication method. these algorithms were typical preconditioning and domain decomposition schemes. By these algorithms, we reduced roundoff error in computing derivatives using chebyshev collocation methods (ccm). in this paper, some applications of these algorithms are presented.
Pdf Solving Nonlinear Odes With The Ultraspherical Spectral Method The course is planned to cover basics of spectral methods and their applications in solving odes pdes using relaxation methods and taylor series based linearization methods. in particular, methods such as the spectral relaxation method, spectral local linearization method and pseudo spectral methods for parabolic pdes will be discussed. Nonlinear pdes can be discretized spectrally in space to a system of coupled nonlinear odes. non periodic domains can be handled by using orthogonal polynomials but boundary conditions need to be thought about some more!.

In this paper, we aim to propose a pseudospectral colloca tion method that retains the advantages of the usual lobatto, gauss, and radau methods, while avoiding their shortcom ings. Pseudospectral methods are based on discrete function approximations that allow exact interpolation at so called collocation points. the most prominent examples are the fourier method based on trigonometric basis functions and the chebyshev method based on chebyshev polynomials.
