Constructor Detail

Adams6

public Adams6(ODE ode)
Constructs the ODESolver for a system of ordinary differential equations.

Parameters:
ode - the system of differential equations.
Method Detail

initialize

public void initialize(double stepSize)
Initializes the ODE solver and allocates the rate and state arrays. The number of differential equations is determined by invoking getState().length on the superclass.

Specified by:
initialize in interface ODESolver
Overrides:
initialize in class Fehlberg8
Parameters:
stepSize -

step

public double step()
Steps (advances) the differential equations by the stepSize. The ODESolver invokes the ODE's getRate method to compute the rate at various intermediate states. The ODESolver then advances the solution and copies the new state into the ODE's state array at the end of the solution step.

Specified by:
step in interface ODESolver
Overrides:
step in class Fehlberg8
Returns:
the step size
