ImplicitIntegrator< T >::IterationMatrix Class Reference

Detailed Description

template<class T>
class drake::systems::ImplicitIntegrator< T >::IterationMatrix

A class for storing the factorization of an iteration matrix and using it to solve linear systems of equations.

This class exists simply because Eigen AutoDiff puts limitations on what kinds of factorizations can be used; encapsulating the iteration matrix factorizations like this frees the implementer of these kinds of details.
