You may have a look at octave:

For 3D visualisation, you could try octaviz:

  http://octaviz.sourceforge.net/

I used these in the courses at my school, our teacher used and
recommended matlab but I wanted to go with free software. It did a
pretty good job, although it cannot match matlab when it comes to really
extensive 3D plots, animated and all. But you might give it a try.
