I.2.3.1 “changeCoordsA20” method

Method “changeCoordsA20” is used to calculate the coordinates of a point wrt basic or “0” coordinate system:

• The coordinate system on which the method is called is the coordinate system in which the initial coordinates of the point are defined. (Coordinate system “A”.)
• The method has one “CoordA” argument: an Array of three real values corresponding to the initial coordinates of the point in coordinate system “A”.
• The method returns a “Coord0” Array of three real values corresponding to the coordinate of the same point, but expressed wrt basic coordinate system “0”.

The method is called as follows:
