      public static double Pam3dRangeCalc(Coordinate3d a, Coordinate3d b)
      Given two Coordinate3d objects, return the distance between them.

    • dist

      public static double dist(double[] a, double[] b)
      Given two N-element vectors representing positions, return the distance between them. This is just the L2-norm of the two vectors. see See also CoordUtils.norm().

    • dist

      public static double dist(double[] a, double[] b, int n)
      Given two N-element vectors representing positions, return the distance between them. This is just the L2-norm of the two vectors. This one differs from the one above in the N is specified explicitly.
