Class Matrix

  • java.lang.Object
    • Jama.Matrix
      • samer.maths.Matrix
  • All Implemented Interfaces:

    public class Matrix
    extends Jama.Matrix
    implements Mat
    Represents a bundling of a Jama.Matrix with Viewable bits. Create one of these and you can either keep it invisible, expose its UI yourself, or let the Viewable framework expose a default viewer automatically
