Welcome to the numerical-mooc wiki!

This repository is the core of the "Practical Numerical Methods with Python course. Each course module consists of a set of IPython Notebooks (links below to the rendered notebook on nbviewer), practice exercises and a coding assignment. To access the practice problems and assignment, you need to register in the GW Online course platform.
