DoubleSparseArrayVector (Nuiton Matrix

java.lang.Object
- org.nuiton.math.matrix.DoubleSparseArrayVector

All Implemented Interfaces:

SparseVector, Vector
```
public class DoubleSparseArrayVector
extends Object
implements SparseVector
```
Permet de stocker des données à une position lineaire et de la redemander. Cette classe ne gére que les données lineaire. L'avantage de cette classe est de ne conserver que les elements differents de la valeur par defaut, ce qui minimize la taille du tableau necessaire a conserver les données.
