generic-rk's Issues

There Seems to be Too Much Error with Fehlberg Methods

There may be a bug in the Fehlberg Methods (4/5 and 7/8). They need to be double checked for errors.

Add Model Option for Pendulum to use Gravity

Right now the acceleration calculation for pendulum is determined via formula based on position which makes the pendulum do some weird things if it goes too high, it would be beneficial to create a new pendulum update derivs method to calculate acceleration based on a gravity term so that the strange behavior would cease to exist.
