Я пытался в течение нескольких дней попытаться скомпилировать функцию ODEINT Integrated_adaptive() внутри класса. Если я беру функцию вне класса и имею общие имена функций, то программа компилируется и работает так, как требуется. (out — это просто вывод в файл, который был определен ранее)
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();
}
У меня есть функция с именем rhs и другая с именем 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 определяется в заголовке следующим образом
typedef boost::array< double , 16 > state_type;
Вывод ошибки был:

Если вам нужно, чтобы я что-то объяснил, просто дайте мне знать, и я постараюсь сделать то, что я говорю, яснее.
Спасибо
