IdPt2D

| HOME | BACK |

Overview

IdPt2D is an object which consists an ID number, two double precision numbers for x and y coordinate, and a standard deviation.  IdPt2D can also be used as a general data structure, though.

 

Member data

Name Data type Meaning
id int ID number
x double x coordinate
y double y coordinate
sd double standard deviation

 

Operator

no operator provided

 

Construction function

{IdPt2D} ret  =  IDPT2D([{int} argm1, {double} argm2, {double} argm3, {double} argm4])

argm1 = Point ID               (default = 0)

argm2 = x coordinate           (default = 0)

argm3 = y coordinate           (default = 0)

argm4 = standard deviation     (default = 0)

Example:

->pt_1 = IdPt2D() a deafult IdPt2D object (id = 0, x = 0, y = 0, sd = 0.00)

->pt_1 = IdPt2D(10, 52.3, 65.2, 0.05)

an IdPt2D object (id = 10, x = 52.3, y = 65.2, sd = 0.05)

 

Lfunction

object.ID()   =  {int} left-value

object.X()    =  {double} left-value

object.Y()    =  {double} left-value

object.SD()   =  {double} left-value

Example:

->pt_1.id() = 5009

->pt_1.sd() = 1.25
