----------------------------------
Ah, so there is a mailing list. I guess I should have looked a little harder.
I'll bring it up there.
> Strange deprecations in API
> ---------------------------
>
> Key: MATH-719
> URL: https://issues.apache.org/jira/browse/MATH-719
> Project: Commons Math
> Issue Type: Bug
> Affects Versions: 2.0, 2.1, 2.2
> Reporter: Peter Bloem
> Priority: Minor
> Labels: api-change, deprecated
>
> Sorry if this doesn't belong here. I couldn't find any sort of mailing list
> or other feedback mechanism on the website.
> RealMatrix has some very odd deprecations. In particular inverse(),
> getDeterminant() and isSingular(). The last has the message:
> bq. Deprecated. as of release 2.0, replaced by the boolean negation of new
> LUDecompositionImpl(m).getSolver().isNonSingular()
> That's an implementation, not an interface. The whole point of having an
> interface is that
> * I can query whether a matrix is singular withou having to know about
> LUDecompositions
> * You guys can change the implementation of isSingular() if something better
> pops up without us guys having to change our code.
> I'm not using these methods now, because they're deprecated, but I've
> basically recreated them in as static methods in a utility class. Wouldn't it
> be much better to just put code from the deprecation message into the method
> and remove the deprecation?
