Class TrapezoidalRule

java.lang.Object

repicea.stats.integral.NumericalIntegrationMethod

repicea.stats.integral.TrapezoidalRule

All Implemented Interfaces:

java.io.Serializable

public final class TrapezoidalRule
extends NumericalIntegrationMethod

The TrapezoidalRule class implements the trapezoidal rule integration method. The resolution parameter in the constructor sets the distance between the x values. The class is adapted to resolution that does not perfectly match the range of the integral.
