Class Overview

Represents a dense normalized matrix M[i,j] where each Mij item of the matrix has a value (default is 0). When a matrix item is observed using getItem method, it is normalized, that is, divided by the total sum of all items. It can be also be scaled by setting a scale factor.

Summary

Constants
double	DEFAULT_SCALE_FACTOR	The default scale factor.
