• Merging the eastern and western sections of Wrangel Island near the Bering Strait
(cut by the 180-degree meridian) into a single polygon with longitudes ranging from
slightly less than 180 to slightly greater than 180.
• Eight additional edits to pull apart landmasses with points of contact and remove
coastal "spikes."
Map Limit Syntaxes Removed
The following syntaxes are obsolete. An error occurs if you use them.
• pcolorm(Z)
• pcolorm(Z,gratsize)
• surfacem(Z)
• surfacem(Z,gratsize)
• surflm(Z)
• surflm(Z,s)
• surfm(Z)
• surfm(Z,gratsize)
These syntaxes displayed a data grid with geographic limits that matched the map
latitude and longitude limits in the current map axes. Using the old syntaxes correctly
involved knowing the latitude and longitude limits of your data and matching them to
the values listed under maplatlimit and maplonlimit in the map axes properties. We
have replaced these syntaxes with a more direct approach that requires you to enter the
latitude and longitude limits for the data grid.
Compatibility Considerations
The table below suggests alternative code to replace the obsolete syntaxes. In the
following table, Z is a regular data grid (a 2-D array of class double) and gratsize is a
two-element vector specifying the size of the graticule on which Z displays:
gratsize = [number_of_parallels number_of_meridians]
h is a handle to the surface that is displayed. And latlim and lonlim are the
geographic limits of the data grid (in degrees):
latlim = [southern_limit northern_limit]
