class | MultiShapeletFunctionEvaluator |
Evaluates a ShapeletFunction.
This is distinct from ShapeletFunction to allow the evaluator to construct temporaries and allocate workspace that will be reused when evaluating at multiple points.
A ShapeletFunctionEvaluator is invalidated whenever the ShapeletFunction it was constructed from is modified.
