>                 Key: MATH-870
>                 URL: https://issues.apache.org/jira/browse/MATH-870
>             Project: Commons Math
>          Issue Type: Improvement
>    Affects Versions: 4.0
>            Reporter: S=C3=A9bastien 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 ag=
reed [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 sp=
arse 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.
