- org.nuiton.math.matrix.DoubleSparseHashVector

All Implemented Interfaces:

SparseVector, Vector
```
public class DoubleSparseHashVector
extends Object
implements SparseVector
```
Permet de stocker des données differente de la valeur par defaut (0.0) dans une Map<int, double>. L'implantation pcj ne supporte pas la modification de la valeur par defaut. On permet que la matrice est plus de Integer.MAX_VALUE cellules mais on ne permet pas que la matrice est plus que Integer.MAX_VALUE valeur différente que le default value. Created: 05 septembre 2012
