Constructor Details

ScalarTurboEvaluator

public ScalarTurboEvaluator(MathExpression me)

ScalarTurboEvaluator

public ScalarTurboEvaluator(MathExpression me,
 boolean useWideningVars)

USE THIS ONLY IF YOU KNOW WHAT YOU ARE DOING!

Parameters:

me - The root MathExpression

useWideningVars - If true, you want the turbo evaluator to pass the variables to the evaluator with a widening approach. If false, it will pass it with an array based approach.
