package com.singularsys.extensions.fastreal
Fast evaluation routines over doubles, can be up to ten times faster than standard Jep. 
 // Construct the compiler/evaluator
 RpEval rpe = new RpEval(jep);
 // Compile an expression
 RpCommandList commands = rpe.compile(expression);
 // Get a reference number for the "x" variable
 int xRef = rpe.getVarRef("x");
 // loop
 for(double x=-1.0;x<=1.0;x+=0.01) {

        // set the value of "x"
        rpe.setVarValue(xRef,x);

        // evaluate
        double res = rpe.evaluate(commands);
 }
