In matlab code, for example RK45 is an adaptive solver.
The mechanisim is that every time, use RK4 get a solution, use RK5 to get
another, check if abs(RK4-RK5)> error1 that you set. if it is, cut interval
into half, if maintain the interval. Actually there are plenty of adaptive solvers, you
don't
need to program by yourself.

: 关键是如何确定步长。
: 没有学过计算数学,
: 还请大虾指点一下有什么网上资源或者书比较好。
