Description

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.

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.
