Matlab Tutorial

Matlab is one of the best tools for designing machine learning algorithms and many of the class assignments and class projects will be easiest to implement and explore with it. Alternatively, it is possible to use other mathematical software like Mathematica or MathCad although these will be much more awkward. Furthermore, it is possible to use C/C++ or Java as the implementation platform but you will require matrix libraries.

Matlab is available to the Columbia community through AcIS. You just connect (i.e. using ssh) to an AcIS CUNIX machine like:
ssh -lyourusername
And then run 'matlab' (which lives in /opt/local/bin/matlab).

See the following for more details (Windows or Unix):

The Columbia University Computer Science department also has Matlab available on various Unix machines (in /usr/local/bin/matlab).
