Umm...you have been able to run matlab for years on a windows mobile.
This is MathCAD...

It is a totally different program. Matlab is essentially a programming language for complex mathematical/engineering problems. Mathcad is an interesting program. It is essentially a calculation program that uses a worksheet interface.
Think of being able to write down your mathematical problems on a sheet of paper and having it "fill in" the result. Very handy program for "showing your work" or typing up a mathematical document for work.
