 AXESM  Map axes definition and property settings
 
   AXESM activates a GUI to define a map projection for the
   current axes.
 
   AXESM('PropertyName',PropertyValue,...) uses the map properties
   in the input list to define a map projection for the current axes.
   For a list of map projection properties, execute GETM AXES.  All
   standard (non-mapping) axes properties are controlled using the
   axes command.  For a list of available projections, execute
   GETM MAPPROJECTION.
 
   AXESM(mstruct,...) uses the map structure specified by mstruct
   to initialize the map projection.
 
   AXESM('ProjectionFile',...) uses the m-file specified by
   'ProjectonFile' to initialize the map projection.  If this form
   is used, the input string 'ProjectionFile' must correspond to an
   m-file on the user's path.  The m-file name must correspond in
   case to how 'ProjectionFile' is typed.
