Subject [jira] [Created] (MATH-766) Refactor RealMatrix and proper SparseRealMatrix
Date Wed, 07 Mar 2012 21:52:57 GMT
Refactor RealMatrix and proper SparseRealMatrix
-----------------------------------------------

                 Key: MATH-766
                 URL: https://issues.apache.org/jira/browse/MATH-766
             Project: Commons Math
          Issue Type: Improvement
    Affects Versions: 2.2
            Reporter: sergio brignone


As is in Version 2.2, SparseRealMatrix is identical to RealMatrix. The latest contains methods
that are practically incopatible with sparse implementations (e.g. getData retuns double[][]
... not usefull for sparse matrices). Sugestion: Split RealMatrix into RealMatrix and FullRealMatrix
that extends RealMatrix and update SparseRealMatrix. Refactor AbstractRealMatrix as well.
