* Commercial software support is available from 3rd parties
* The software can be installed on a local desktop, or in a networked environment and run remotely
* It is free (both for academic and commercial use), so it can used after you graduate
* Installation is straightforward
* The license is not restrictive: you can legally modify and improve the software
* There are excellent add-on libraries for almost anything related to data analysis
* It promotes good practice of writing a code file, and then running it (like MATLAB).  The code file documents what you have done, and you can always repeat your analysis on a new data set, or share the code with colleagues.  Other software packages tend to promote a more point-and-click approach, so you can't always retrace your steps.
* There are multicore and 64-bit versions of Python available to process large data sets, and do parallel data processing

You may use any software in the course to complete the assignments and labs. The official course software packages are either MATLAB or Python. Solutions to questions and class discussions will use either programming languange. Please note: the computer laboratories only have MATLAB installed.

Microsoft Excel is not recommended: it cannot perform some of the calculations and plots that you will require in the course, and its accuracy is very poor (the article documents several functions that produce incorrect results).


A detailed sequence of software tutorials is available. It is expected that you work through these tutorials on your own.
