Luc Maisonobe commented on MATH-870:
------------------------------------
Considering point 1 in your message, the text you proposed has been added on
the classes (not only OpenMapRealMatrix and OpenMapRealVector), but also on the
interfaces and on the "Field" classes too.
Considering point 2, I don't understand what you want us to demonstrate. Do you
want us to set up a matrix multiplication with a NaN that get not propagated or
something like that? What would this test bring?
Considering point 3, I have not seen any special handling in OpenMapRealMatrix.
Dis you write about the ebeDivide and ebeMultiply methods in OpenMapRealVector?
Point 4 has been addressed.
> 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.
