public abstract class DynamicMatrixEvaluator extends MotionEvaluator1<Matrix>
Evaluates a DynamicMatrix over time.
The result of evaluating will be a
Motion<Matrix> representation of this
matrix at the specified JulianDate. This evaluator will attempt to provide
derivatives of the matrix up to the requested order.

Gets a version of this evaluator that caches the previously computed value so that if it is evaluated
twice at the same date the computation is done only once.

This method is called by EvaluatorGroup to create a caching version of an evaluator
that is shared between multiple computations.
To implement this method in your own evaluator, construct and return a caching version of the evaluator's base class.
For example, if your evaluator implements IEvaluator1 directly, return an instance of
CachingEvaluator. In many cases, such as when implementing a PointEvaluator
this method does not need to be overridden because the default implementation returns an appropriate
caching wrapper already. If you do not want the last value computed by your evaluator to ever be cached, or
if your evaluator does its own caching internally, this method can return this.
Shows an example implementation in an evaluator that implements IEvaluator1
directly, where T is double.
