Change to avhrrlambert Function Behavior When No Data Is Available
In previous releases of the toolbox, avhrrlambert would error if the quadrangle defined
by latlim and lonlim (when projected to form a polygon in the appropriate Lambert
Equal Area Azimuthal projection) failed to intersect the bounding box of the data in the
projected coordinates. In this release, avhrrlambert does not error when this occurs but
returns empty matrices.
Compatibility Considerations
If you depend on avhrrlambert to error when there is no data in your quadrangle, you
will need to change your code.
Enhancements to Mapping Toolbox User's Guide
Several sections of the chapter Understanding Geospatial Geometry have been rewritten
and new material has been added to better explain critical topics such as ellipsoid
models, units of and notations for angles and length, and the conversions that are
possible between various units. There is also a new section, Exporting Vector Geodata,
explaining and illustrating how to use the new kmlwrite and makeattribspec
functions.
Functions deg2rad and rad2deg No Longer Convert Complex to Real
In prior versions, when given complex inputs, functions deg2rad and rad2deg issued a
warning and then converted their inputs to real. Now they no longer do either of these
things.
Compatibility Considerations
In the unlikely event of complex input, these functions simply scale the imaginary part
by the same factor as the real part. For example, in R2007a and earlier releases, they
behave as follows:
>> deg2rad(180i)
Warning: Imaginary parts of complex ANGLE argument ignored
