orthpol 0.2.19

Python wrapper for the ORTHPOL package

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

Requirements

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.

Installation

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 setup.py install

• Modified interface to account for changes in the SpectralToolbox

• Complete integration of orthpol into SpectralToolbox

0.2.1:

• Porting to python 3.x and back compatibility with python 2.x

• Automated installation through pip

0.2.2:

• Bug fix

0.2.13:

• Improved install script.
