First order stiff ordinary differential equation solver in matlab

The following Matlab project contains the source code and Matlab examples used for first order stiff ordinary differential equation solver. Implicit methods are important in numerical solution of stiff ODEs due to the instable nature of explicit methods. We wrote a program of a general one-dimensional implicit-solver including diagonally implicit case.

Dct Matlab Code

A discrete cosine transform (DCT) expresses a finite sequence of data points in terms of a sum of cosine functions oscillating at different frequencies. DCTs are important to numerous applications in science and engineering, from lossy compression of audio (e.g. MP3) and images (e.g. JPEG) (where small high-frequency components can be discarded), to spectral methods for the numerical solution of partial differential equations.
