Class OpVect

  • public class OpVect
extends java.lang.Object
    Class OpVect offers a list of static methods that deal with numeric vectors;
    it allows the user to read vectors from the keyboard, and to calculate the
    dot, cross and mixed product, as well as the modulus of a vector and the distance
    between two points.
