CySparse

A fast sparse matrix library for Python/Cython.

Only Python 2.7 is supported for now. We plan to support Python 3.3 later.

Dependencies

Python version

For the Python version:

• NumPy;

If you intend to generate the documention:

• Sphinx;
• sphinx_bootstrap_theme;

To run the tests:

• nose or unittest;

To run the performance tests:

[TODO]

Cython version

For the Cython version, include everything needed for Python and add:

• Cython;
• cygenja;

Installation

Python version

1. Clone repository (git clone https://github.com/PythonOptimizers/cysparse.git) or copy source code.
2. Install Python dependencies.
3. Copy cysparse_template.cfg to cysparse.cfg and adapt it to your needs.
4. Invoke python setup.py install.

Cython version

[TODO]

Run tests

Invoke:
