Luc Maisonobe resolved MATH-870.
--------------------------------
Resolution: Won't Fix
The classes have been un-deprecated as per r1569825, after a decision on the
developers mailing list.
We basically consider that we should not try to find a perfect theoretical
answer here but simply do as most other linear algebra libraries do: ignore the
problems of NaNs and infinities in sparse matrices and vectors. This behavior
seems to be well accepted in all current libraries.
> Deprecate interfaces and implementations of sparse vectors and matrices

> Key: MATH-870
> URL: https://issues.apache.org/jira/browse/MATH-870
> Project: Commons Math
> Issue Type: Improvement
> Affects Versions: 4.0
> Reporter: Sébastien Brisard
> Priority: Minor
>
> Recently, many problems have been found out with class
> {{OpenMapRealVector}} (see MATH-803 and MATH-821), to the point that the
> complete removal of this class in upcoming versions (as of 4.0) has been
> agreed [markmail|http://markmail.org/thread/bseyswf7qqrgatru].
> Since it now becomes useless, {{SparseRealVector}} will also be removed. For
> the sake of consistency, {{SparseFieldVector}} will also be removed.
> Furthermore, it is expected that the same kind of bugs will occur with sparse
> implementations of real/field matrices, which will also be removed.
> In version 3.1, the following classes and interfaces will be deprecated
> * {{SparseRealVector}}
> * {{OpenMapRealVector}}
> * {{SparseFieldVector}}
> * {{SparseRealMatrix}}
> * {{OpenMapRealMatrix}}
> * {{SparseFieldMatrix}}
> They will be completely removed in version 4.0.
