I have recently added code for POD (proper orthogonal decomposition) on GitHub. If you do find the code useful, you may write to me or acknowledge me.
The code is in https://github.com/wtvrinc/POD.
I will soon be adding other codes that I use on a regular basis. Feel free to contact me for help, but I cannot guarantee I will be useful.
I am a big advocate of Python programming language. How I feel about Python can easily be summarised with this xkcd cartoon.
