Recall that I wrote about Wolfram Research offering a Home Edition version of Mathematica 7. A lot of engineering and scientific applications use MATLAB too. However, the only way to get the cheap edition of MATLAB is to be a student. Otherwise, you’d have to pay about $2000 for the software license. I believe that the Mathworks should consider offering a Home Edition of MATLAB too for those who want to tinker with some engineering and scientific computations in a non-commercial setting.
