问题描述

我想利用的利用本征3 作为的错误,第一个是

我试图钻进去,但我没有足够的理解发生了什么事情才能够解决我的code的。由于odeint库文档明确

I believe this shouldn't be too hard to get working even if odeint doesn't support Eigen natively.

解决方案

You only need to replace the definition of the stepper by

runge_kutta_dopri5<state,double,state,double,vector_space_algebra> stepper;

Eigen should work out of the Box with the vector_space_algebra but you need to specify them manually. In the next odeint version we have a mechanism for automatically detecting the algebra.

Btw. youe definition of the ODE is not correct, you need a reference for the derivatve

stepper.do_step([](const state &x, state &dxdt, const double t) -> void {
    dxdt = x;
}, X0, 0.0, xout, 0.01);
