Class OverlappingEventsTest

java.lang.Object
  org.apache.commons.math3.ode.events.OverlappingEventsTest

All Implemented Interfaces:: FirstOrderDifferentialEquations

public class OverlappingEventsTest
extends Object
implements FirstOrderDifferentialEquations
extends Object
implements FirstOrderDifferentialEquations

Tests for overlapping state events. Also tests an event function that does not converge to zero, but does have values of opposite sign around its root.

Constructor Summary
`OverlappingEventsTest()`

Method Summary
`void`	`computeDerivatives(double t, double[] y, double[] yDot)`
`int`	`getDimension()`
`void`	`test(int eventType)` Test for events that occur at the exact same time, but due to numerical calculations occur very close together instead.
`void`	`testOverlappingEvents0()` Test for events that occur at the exact same time, but due to numerical calculations occur very close together instead.
`void`	`testOverlappingEvents1()` Test for events that occur at the exact same time, but due to numerical calculations occur very close together instead.

Method Detail

testOverlappingEvents0

public void testOverlappingEvents0()
                            throws DimensionMismatchException,
                                   NumberIsTooSmallException,
                                   MaxCountExceededException,
                                   NoBracketingException

Test for events that occur at the exact same time, but due to numerical calculations occur very close together instead. Uses event type 0. See EventHandler.g(double, double[]).

Throws:: DimensionMismatchException; NumberIsTooSmallException; MaxCountExceededException; NoBracketingException

testOverlappingEvents1

public void testOverlappingEvents1()
                            throws DimensionMismatchException,
                                   NumberIsTooSmallException,
                                   MaxCountExceededException,
                                   NoBracketingException

Test for events that occur at the exact same time, but due to numerical calculations occur very close together instead. Uses event type 1. See EventHandler.g(double, double[]).

Throws:: DimensionMismatchException; NumberIsTooSmallException; MaxCountExceededException; NoBracketingException

test

public void test(int eventType)
          throws DimensionMismatchException,
                 NumberIsTooSmallException,
                 MaxCountExceededException,
                 NoBracketingException

Test for events that occur at the exact same time, but due to numerical calculations occur very close together instead.

Parameters:: eventType - the type of events to use. See EventHandler.g(double, double[]).
Throws:: DimensionMismatchException; NumberIsTooSmallException; MaxCountExceededException; NoBracketingException
