 GetCoordinates
 return the coordinate attribute of a Vector

 Calling Sequence GetCoordinates(v)

Parameters

 v - (optional) Vector

Description

 • The GetCoordinates(v) calling sequence returns the coordinate system attribute of the Vector v.  If v is not specified, the default coordinate system is returned.
