MatrixJep Console Example Applet

The JEP Java Expression Parser can parse and evaluate mathematical expressions. The DJep package adds differentation, simplification vectors and matrices, abstract groups and several other advanced features.

Below is a console for the MatrixJep part of the DJep package, which adds vector handling, including dot product '[1,2,3].[1,2,3]', cross product '[1,2,3]^^[4,5,6]', matrix multiplication '[[1,2],[3,4]]*[1,1]', and differentation 'diff([x,x^2,x^3],x)'.
