SimpsonRule class base
The "Simpson rule" is a technique for approximating the value of a definite integral.
This algorithm requires the intervals parameter, which indicates how many partitions have to be computed by the algorithm.
Note that intervals must be an even number. If intervals is not even, a
NumericalIntegrationException object is thrown.

Methods
-
evaluateFunction(
double x) → double -
Evaluates the given function on the
xpoint.inherited -
integrate(

Calculates the numerical value of the definite function integral
between lowerBound and upperBound. Returns a Record object whose
members are:
