Method “changeCoordsA20” is used to calculate the coordinates of a point with respect to 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 with respect to basic coordinate system “0”.
The method is called as follows:
coords0=csA.changeCoordsA20(coordsA)
