Chebyshev polynomial based spectral methods of PDEs.

Project description


**chebpy** is a python package for spetral methods of PDEs based on
Chebyshev series.


1. Install


$ easy_install chebpy



$ tar -xvf chebpy-xxx.tar.gz
$ cd chebpy-xxx
$ python install

Required packages:

* `numpy`: chebpy heavily depends on numpy.
* `scipy`: advanced algorithms, such as scipy.fftpack.dct.

2. APIs

**Chebyshev series construction**

* cheb_polynomial_recursion
* cheb_polynomial_trigonometric
* cheb_polynomial_series

**Fast Chebyshev transform**

* cheb_fast_transform
* cheb_inverse_fast_transform

**Chebyshev differentiation**

* cheb_D1_mat
