Class IMatrixCell

java.lang.Object
  infomat.vectorspace.IMatrixCell

All Implemented Interfaces:

IVectorIndex

public class IMatrixCell
extends java.lang.Object
implements IVectorIndex

An element in a IMatrix. In many types of applications, as Information Retrieval (IR) for instance, the IMatrix is very sparse. Only the non zero elements are stored.
