Expanding latitude-longitude quadrangle with bufgeoquad function
The bufgeoquad function expands the latitude and longitude limits of geographic
quadrangle, accounting for spherical topology.
Spheroid class methods for 3-D coordinate transformations
The three spheroid classes, oblateSpheroid, referenceEllipsoid, and
referenceSphere, include 3-D transformation methods using geodetic and Earth-
Centered Earth-Fixed (ECEF) Cartesian coordinates.
• geodetic2ecef - transforms geodetic to geocentric (ECEF) coordinates
• ecef2geodetic - transforms geocentric (ECEF) to geodetic coordinates
• ecefOffset - Computes Cartesian ECEF offset between geodetic positions
These methods can be used with either degrees or radians.
Compatibility Considerations
If you choose to replace calls to the existing geodetic2ecef and ecef2geodetic
functions with calls to the new methods of the same names, be aware that the methods
use latitude and longitude in units of degrees, but the functions assume units of radians.
Option to use in degrees in unwrapMultipart
The unwrapMultipart function now accepts an optional angle unit string, which can
match either 'degrees' or 'radians'.
Changes in geopoint class
A new collection property, Geometry, has been added to the geopoint class. Its value is
always 'point'.
Compatibility Considerations
• The lat and lon inputs are restricted to either class type single or double. In R2012a,
the lat and lon inputs may be any numeric type.
