I put a 3.0-SNAPSHOT site up at
http://people.apache.org/~bayard/commons-lang/3.0-SNAPSHOT/
Let's you see the current backwards compat changes:

but the component has never had a release and is now inactive. this is a
bit of a shame since (in my experience) it is reasonably widely used.
some work would be needed to prepare it for a release. the build would
need upgradi

Ted, thanks for pointing this out... I'd never seen it before. Glad MTJ did
so well and I note that this isn't even with the optional native BLAS/LAPACK

I've somehow missed much of this discussion, which has got a little confused.
I'll repeat some key facts here:-

- I'm the maintainer of netlib-java
- netlib-java depends on PURE JAVA code, generated by F2J from netlib.org

I think netlib-java might actually be using the CLAPACK version of LAPACK...
the biggest problem with C/Fortran is the array indexing is different for

I suspected as much: that makes JAMA and Colt both deceased. Does anyone know
how to contact the JAMA authors and ask them to make this explicit in the

I suppose these interfaces would extend Real{Matrix, Vector} ?

Exactly. In future, it might be wise to use the "subclass return trick" here

Perhaps... but the shape is probably more important than the sparsity score

getSparseShapeOrClassOrWhateverItShouldBeCalled would be very, very helpful.

Go for it.
