org.apache.commons.math3.ode.JacobianMatrices.JacobiansSecondaryEquations

All Implemented Interfaces:

SecondaryEquations

Enclosing class:

JacobianMatrices

private class JacobianMatrices.JacobiansSecondaryEquations
extends java.lang.Object
implements SecondaryEquations

Local implementation of secondary equations.

This class is an inner class to ensure proper scheduling of calls by forcing the use of JacobianMatrices.registerVariationalEquations(ExpandableStatefulODE).

                               DimensionMismatchException

Compute the derivatives related to the secondary state parameters.

Specified by:

computeDerivatives in interface SecondaryEquations

Parameters:

t - current value of the independent time variable

y - array containing the current value of the primary state vector

yDot - array containing the derivative of the primary state vector

z - array containing the current value of the secondary state vector

zDot - placeholder array where to put the derivative of the secondary state vector

Throws:

MaxCountExceededException - if the number of functions evaluations is exceeded

DimensionMismatchException - if arrays dimensions do not match equations settings
