Dear community, I've started on implementing Kalman filter and have once again run into a structural challenge in regards to matrix hierarchy (as with https://issues.apache.org/jira/browse/MATH-435 and https://issues.apache.org/jira/browse/MATH-437 ).
We have two base types of matrices: RealMatrix and FieldMatrix, both extending AnyMatrix. Both RealMatrix and FieldMatrix have a lot of the same functionality, e.g. add, subtract, scalarAdd, scalarMultiply, multiply, preMultiply etc. I think it would be beneficial to try to move these standard matrix methods to AnyMatrix, or at least introduce a new intermediate AnyAlgebraicMatrix (or similar). It would be natural in several aspects to just require an AnyAlgebraicMatrix, e.g. with Kalman filter or repeated squaring, instead of forcing the user to use either RealMatrix or FieldMatrix (or implement almost similar code for both). What do you think about such a reorganization of the matrix hierarchy? Cheers, Mikkel. --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@commons.apache.org For additional commands, e-mail: dev-h...@commons.apache.org
