Class VectorMathOperation

java.lang.Object

com.numericalmethod.suanshu.vector.doubles.dense.VectorMathOperation

All Implemented Interfaces:

java.io.Serializable

public class VectorMathOperation
extends java.lang.Object
implements java.io.Serializable

This is a generic implementation of the math operations of double based Vector. It assumes no knowledge of how a vector is implemented. A particular implementation of Vector can improve performance by taking advantage of having access to the internal members.
