Class ScalarOps

java.lang.Object
  ch.javasoft.smx.ops.ScalarOps

public class ScalarOps
extends Object

The ScalarOps class contains static methods performing operations with a matrix and a scalar. Such operations are for instance scaling all matrix elements with the same factor, or adding a value to each matrix element.
