Constructor Detail

MultipleStepIntegrator

protected MultipleStepIntegrator()

Initializes a new instance.

MultipleStepIntegrator

protected MultipleStepIntegrator(@Nonnull
                                 MultipleStepIntegrator existingInstance,
                                 @Nonnull
                                 CopyContext context)

Initializes a new instance as a copy of an existing instance.

See ICloneWithContext.clone(CopyContext) for more information about how to implement this constructor in a derived class.

Parameters:

existingInstance - The existing instance to copy.

context - A CopyContext that controls the depth of the copy.

Throws:

ArgumentNullException - Thrown when existingInstance or context is null.

Method Detail

updateSavedDerivatives

public abstract void updateSavedDerivatives(@Nonnull
                                            double[] derivativeCorrections)

This method is used in order to update the last step's derivatives with any post integration corrections.

Parameters:

derivativeCorrections - The corrections to the last step's derivatives.
