Class LegacyDoubleSparseHashVector

java.lang.Object
org.nuiton.math.matrix.LegacyDoubleSparseHashVector
All Implemented Interfaces:
SparseVector, Vector
public class LegacyDoubleSparseHashVector extends Object implements SparseVector
This class is a copy of DoubleSparseHashVector Vector class, as in version 2.8.0. When calling MatrixND.sumOverDim(int) on a MatrixND object that uses this class as data storage, the legacy method AbstractMatrixND.sumOverDim(int) will be called instead of the optimized algorithm implemented in MatrixNDImpl.sumOverDim(int).
