IdPt1D

| HOME | BACK |

Overview

IdPt1D is an object which consists of an ID number, one double precision value, and a standard deviation.  It is originally used for a vertical ground control point, with an ID and a standard deviation.  IdPt1D can also be used as a general data structure, though.

 

Member data

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

 

Operator

no operator provided

 

Construction function

{IdPt1D} ret  =  IDPT1D([{int} argm1, {double} argm2, {double} argm3])

argm1 = Point ID               (default = 0)

argm2 = x coordinate           (default = 0)

argm4 = standard deviation     (default = 0)

Example:

->pt_1 = IdPt1D() a default IdPt1D object (id = 0, x = 0, sd = 0.00)

->pt_1 = IdPt1D(10, 525.236, 0.05)

an IdPt1D object (id = 10, x = 525.236, sd = 0.05)

 

Lfunction

object.ID()   =  {int} left-value

object.X()    =  {double} left-value

object.SD()   =  {double} left-value

Example:

->pt_1.id() = 5009

->pt_1.sd() = 1.25

 

Class function
