New Angle Conversion Functions
Two new functions, radtodeg and degtorad, replace older functions rad2deg and
deg2rad. They are functionally identical.
Compatibility Considerations
The older functions, rad2deg and deg2rad, will continue to work, but when writing new
code the newer versions are recommended.
Expanded Support for GSHHS Global Coastline Data
The gshhs function now supports Versions 1.4 and later of the Global Self-Consistent,
Hierarchical, High-Resolution Shoreline Database (GSHHS).
New Behavior for polymerge when Three or More Line Segments Have
Common End Point
The behavior of the polymerge function has changed in cases of three or more distinct
parts with a common end point. In such cases, the choice of which parts to merge is
ambiguous; therefore, none of the corresponding parts are connected at that common
point.
Compatibility Considerations
In previous releases, if three or more parts shared a common end point, the polymerge
function attempted to merge them. The result, however, was unspecified and sometimes
obviously wrong.
Automatic Conversion of Latitude Limits to Ascending Order
The functions axesm and setm require that the latitude limits in the 'MapLatLimit'
property be provided in ascending order. If you enter the limits in descending order,
these functions will now automatically convert the limits to ascending order, and return
a warning message notifying you of this change.
