Rig_Ulam_Sage

Python code to compute rigorous invariant measures for dynamical systems via Ulam approximation.

Installation instructions

This code requires Sage and joblib. To install joblib inside a Sage installation, do the following:

1. Download the joblib source from https://pypi.python.org/pypi/joblib#downloads and unpack it somewhere.
2. Run the command sage -python setup.py install from the folder where you downloaded it.

For instance:

cd /tmp
wget https://pypi.python.org/packages/source/j/joblib/joblib-0.8.4.tar.gz
tar xzf joblib-0.8.4.tar.gz
cd joblib-0.8.4
sage -python setup.py install

Joblib is now installed alongside Sage. You can delete the installation folder.

Now run sage and try running an example file with the command %run "example_ulam_L1.py".

To build the documentation, use

cd doc
make html

You can then view the file doc/build/html/index.html with your favorite browser.
