Re: [ojAlgo-user] question re: custom MatrixStore<>

[Jonathan S. <jo...@ma...>]

Rather than provide all of the context, quite simply if I create a class
that implements MatrixStore<Double> the newly created class does not have
the same set of operations that the AbstractMatrix class provides (such as
invert()).   Is MatrixStore<> the correct way to create an extensible
matrix class?  Secondly, is there a way to get the missing operators on the
class through inheritance or something like that?
