Sébastien Brisard created MATH-870:
--------------------------------------
Summary: 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: 3.1, 4.0
Reporter: Sébastien Brisard
Assignee: 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.
