固定步长积分器

固定步长积分器是一种简单的积分器，每步积分的时间间隔相同。

成员函数说明

◆ integrate() [1/3]

template<typename Func >

errc_t ast::ODEIntegrator::integrate	(	int	ndim,
		Func	func,
		double *	y,
		double &	t,
		double	tf )

inline

积分ODE

积分ODE，将积分结果存储在y和t中

参数

[in]	ndim	ODE的维度
[in]	func	常微分方程
[in,out]	y	状态向量
[in,out]	t	当前时间
[in]	tf	最终时间

◆ integrate() [2/3]

errc_t ast::ODEFixedStepIntegrator::integrate	(	ODE &	ode,
		double *	y,
		double &	t,
		double	tf )

overridevirtual

参见: ODEIntegrator

int ndim = ode.getDimension();

实现了 ast::IODEIntegrator.

被 ast::ODEVarStepIntegrator 重载.
