Package com.singularsys.extensions.xjep

package com.singularsys.extensions.xjep

Various symbolic utilities. The main class XJep extends the Jep class and exposes several useful symbolic methods. Allows a pre-processing stage where symbolic operations can be performed prior to evaluation. Also allow variables to have equations so we can set f = a x^2 + b x + c

Since:

Jep 3.5 / Extensions 2.0
