Installation

A MATLAB version of the package can be found in the directory /lib/matlab; it can be imported in any script by typing

>> addpath '/path/to/chiexp/directory/lib/matlab'
>> help chiexp

We also provide a Python module contained in the directory lib/python, that can be easily imported with

>>> import sys
>>> sys.path.append('/path/to/chiexp/directory/lib/python')
>>> from chiexp import chisquare
>>> help(chisquare)

To build the documentation locally download the git repository and run make html or make latexpdf from the doc folder. It requires the sphinx-build command so make sure that sphinx is properly installed (pip install sphinx).
