I'm taking a class called Numerical Analysis this semester, and for the projects we are required to use some sort of math software. I have access to three: Maple, Matlab, and Mathematica. Which one would you recommend and why? I've enver used neither one of those for a math class; I did do some image processing with Matlab, but thats a bit different. So far, I've heard that both matlab and maple are more user friendly than Mathematica.

Any suggestions?
