Constructor Detail

RungeKutta4

public RungeKutta4(Ode ode,
                   double tStart,
                   double tEnd,
                   double stepSize)

Create the solver for a give ode object and initial consitions.

Parameters:

ode - the ode object containing the specification of the ode.

tStart - the start time (the independent variable is assumed to be time)

tEnd - the end time (the independent variable is assumed to be time)

stepSize - the size of the step to be used in the solver.
