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
