DJep symbolic differentation and matricies for the Java Equation Parse (JEP)

The Java Equation Parser can parse and evaluate mathematical equations. The DJep package adds facilities for

Differentation
Vectors and matricies
Simplification, printing and several other useful extensions.
Exact calculation over integers, rationals and other abstract groups.
Fast evaluation

Demos

JEP Console the standard JEP Console.
XJep Console adds simplification, and several new functions.
DJep Console allows symbolic differentation.
VectorJep Console allows vector and matrix operations.
MatrixJep Console vectors, matrices and differentation.
Rpe Console Fast evaluator (scaler version).
MRpe Console Fast evaluator (matrix version).
GroupJep Console exact arithmetic over abstract groups such as the integers, rationals, free groups (polynomials), algebraic numbers.
SJep Console Simplification, expansion and conversion to polynomials.
