Thank you for the nice list.

Please mention NumPy/SciPy, at http://www.scipy.org/, and see http://en.wikipedia.org/wiki/Scipy.

SciPy is very important, is actively supported, and has a wide following.

Hi Mr. Nau,

I have already included SciPy in my list.

Thanks Dude, very useful blog

You’re welcome Hersamin.

Algebrus is no freeware.

Sir, do you have a free software for SPSS? Where can I find it in your blog? Thanks..

Hi Sir Landoy,

SPSS is not free. However, there is an alternative to it called PSPP. I think it’s in the list. I haven’t tried it thought.

Guillermo
