Question

我已经尝试了几天尝试在一个类中编译ODEINT的integrate_adaptive（）函数。如果我在类之外使用函数并具有通用函数名，那么程序将根据需要进行编译和工作。（out只是文件的输出，之前已定义过）

void waterbodies::writeInfo(){
    bulirsch_stoer_dense_out< state_type > stepper( 1E-9 , 1E-9 , 1.0 , 0.0 );
    state_type x1 = { 0.0024 , 0.00001 , 0.0008,0.6,100,5,5,4,4,4,4,20000,0,10,10,100 }; // initial conditions
    out.open( Name.c_str() );
    out.precision(16);
    double t = 0.0;
    double max = 100;
    double dt = 0.01;
    boost::numeric::odeint::integrate_adaptive(
            rhs,
            x1 , t , max , dt, write_rhs);
    out.close();
}

我有一个名为rhs的函数，另一个名为write_rhs

void waterbodies::write_rhs( const state_type &x , const double t )
{
    out << t << '\t' << x[0] << '\t' << x[1] << '\t' << x[2] << '\t' << x[3] << '\t' << x[4] << '\t' << x[5] << '\t' << x[6] << '\t' << x[7] << '\t' << x[8] << '\t' << x[9] << '\t' << x[10] << '\t' << x[11] << '\t' << x[12] << '\t' << x[13] << '\t' << x[14] << '\t' << x[15] << std::endl;
}


void waterbodies::rhs( const state_type &x , state_type &dxdt , const double t  )
{}

state_type在标题中定义如下

typedef boost::array< double , 16 > state_type;

错误输出为：

如果你需要我解释一些事情，请告诉我，我会尽力让我说得更清楚。

这个问题已经多次回答：

Using boost::numeric::odeint inside the class

您需要将| ONO | PNO | QTY | |------|-------|-----| | 1021 | 10601 | 4 |和rhs绑定到当前类：

write_rhs

我需要做些什么才能使odeint集成函数在另一个类中编译？
