I.2 The “CoordSys” class

Chapter I.2
The “CoordSys” class

It may be practical to manipulate coordinate systems at post-processing level. Therefore, a “CoordSys” class devoted to the manipulation of coordinate systems is proposed. The methods defined in that class are described in sections I.2.2 and I.2.5. A list of the methods defined in “CoordSys” class is given in Table I.2.1.

Table I.2.1: The different methods that have been defined in “CoordSys” class. Methods marked with “(s)” are singleton methods.


(FeResPost list of classes is given in Table 1 page 27.)
