Class DOT

java.lang.Object

org.ojalgo.array.operation.DOT

All Implemented Interfaces:

ArrayOperation

public abstract class DOT
extends Object
implements ArrayOperation

The ?dot routines perform a vector-vector reduction operation defined as Equation where xi and yi are elements of vectors x and y.
