 Easy to compile, fast ODE integrators as C++ classes
 
 This repo contains a collection of C++ classes for solving systems of ordinary differential equations (ODEs) in autonomous form. Documentation is [here](https://wordsworthgroup.github.io/libode/). All of the solvers are single-step, Runge-Kutta-like methods. There are explicit, adaptive solvers up to the ninth order. The repository also includes Rosenbrock methods, a singly-diagonal implicit Runge-Kutta (SDIRK) method, and several fully implicit Runge-Kutta methods. However, only a few of the implicit methods have solid adaptive time steppers at this point. With the current collection of solvers and features, `libode` is well suited to any non-stiff systems and to stiff systems that are tightly coupled and have a known Jacobian (ones that don't require sparse or banded matrix routines). It's been useful for solving the same system a huge number of times with varying parameters, when the speed advantage of parallel C++ might be worth it.
