        	:target: https://travis-ci.org/walchko/pyrk
        
        A simple implementation of `Runge-Kutta <https://en.wikipedia.org/wiki/Runge%E2%80%93Kutta_methods>`_
        for python.

        	pip install pyrk
        
        
        Develop
        ~~~~~~~~~~
        
        ::
        	git clone https://github.com/walchko/pyrk
        	cd pyrk

        Usage
        --------
        
        See the examples in the `docs <https://github.com/walchko/pyrk/blob/master/doc/runge-kutta.ipynb>`_ folder or a simple one::
        
        	from __future__ import division, print_function
        	from pyrk import RK4
        	import numpy as np
        	import matplotlib.pyplot as plt
        
        	def vanderpol(t, xi, u):
        		dx, x = xi
        		mu = 4.0 # damping
        
        		ddx = mu*(1-x**2)*dx-x
        		dx = dx
        
        		return np.array([ddx, dx])
        
        	rk = RK4(vanderpol)
        	t, y = rk.solve(np.array([0, 1]), .01, 200)
        
        	y1 = []
        	y2 = []
        	for v in y:
        		y1.append(v[0])
        		y2.append(v[1])
        
        	plt.plot(y1, y2)
        	plt.ylabel('velocity')
        	plt.xlabel('position')
        	plt.grid(True)
        	plt.show()
