> 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.
