Python wrapper for the ORTHPOL package

Project description

This is the orthpol package. It is a frontend to the Fortran package orthpol written by W Gautschi [1].

[1] Gautschi, W. (1994). Algorithm 726: ORTHPOL–a package of routines for generating orthogonal polynomials and Gauss-type quadrature rules. ACM Transactions on Mathematical Software (TOMS), 20(1), 21–62. doi:10.1145/174603.174605






The package depends on a C++ porting of the Fortran library orthpol. Thus both C++ and Fortran compilers must be installed on the machine. The code is tested using the GCC compiler suite or clang for the compilation and linking of C++ code, and the gfortran compiler for the Fortran part of the code.


Make sure to have an up-to-date version of pip:

$ pip install –upgrade pip

Automatically install the software using the command:

$ pip install orthpol

If this doesn’t work, the package can be manually downloaded and installed through the following procedure:

$ cd <download_dir>

$ pip download orthpol

$ tar xzf orthpol-X.X.X.tar.gz

$ cd orthpol-X.X.X

$ python install

Change Log

  • Initial python porting (working only for python 2.x)
  • Porting to python 3.x and back compatibility with python 2.x
  • Automated installation through pip
  • Bug fix
  • Improved install script.
  • Fixed bug in Py_polyeval. Access to data is now done only through PyArray_GETPTR macros.
  • Added function to compute monomial coefficients
