Method Detail

update

public double update(double t)

RungeKuttaの制御ルーチン 入力：t_n,dt_n 出力：(y_{n+1}),dt_{n+1} 現在は固定刻み幅だが，rk4を呼び出す部分を制御することにより 変動刻み幅のRungeKuttaにできるはず そのためにdt_{n+1}も出力するようにしている tは内部では変更しているが，値渡しなのでConductorのtはt=t_nのまま

Specified by:

update in class VariableList

Parameters:

t -

Returns:

time step

prepare

public void prepare(double min,
                    double max,
                    double dyY,
                    double duration)

Description copied from class: VariableList

call all Euler's start()
dt controlの閾値を設定し、全てのVariableのstart()を呼び出す。

Overrides:

prepare in class VariableList

Parameters:

min - minimum time step

max - maximum time step

dyY - restrict maximum dy/Y and adjust time step

duration - to calculate
