equation - the equation to use.

Milne

public Milne(double timeStep,
     DifferentialEquationInterface equation,
     short integrationMethod,
     int startingSubSteps)

constructs a new Milne integrator, indicating the starting method and number of substeps

Parameters:

timeStep - the timeStep to use in the estimation.

equation - the equation to use.

integrationMethod - the primer integrator to use

startingSubSteps - the number of substeps per timestep during starting of the integrator

Method Detail

next

public double[] next(double x)

Description copied from class: CachingNumericalIntegrator

The integrators that extend the CachingNumericalIntegrator calculate the value of y(x+timeStep) just based on the x-value. They retrieve y(x), y(x-timeStep), etc. or y(k), y(k-1) all from the cache.

Specified by:

next in class CachingNumericalIntegrator

Parameters:

x - the x-value to use in the calculation

Returns:

the value of y(x+timeStep)
