R2010b
10-10
• When the axes contains Mapping Toolbox contour objects, cdelta is ignored and the
resultant colormap contains the same number of colors as the original colormap. The
ColorAlignment is set to 'center' for contour lines and 'ends' for filled contours
and cannot be modified.
• After you have created a contourcmap, if you change the figure's colormap, the
colorbar will change colors. The contourlines and the fill will not change colors. To
work around this problem, do not set the figure colormap directly; set contourcmap.
• You can now set the 'Colorbar' parameter to 'off' to remove it from your map.
Compatibility Considerations
The original syntax, with the colormap string and cdelta in the reverse order, still
works. In a future release, this undocumented syntax will be removed.
Change in Behavior for bufferm
If you specify 'out' for the direction string when calling the bufferm function,
the returned buffer zone will include all points outside the polygon within a specified
distance of its edge. In previous releases, the returned buffer zone also included the
points within the polygon.
Compatibility Considerations
If you have code that specifies 'out' for the direction string, you now receive only
the region outside the polygon but not the polygon itself. If you want to receive the union
of the polygon and the buffer zone, as you did in previous releases, use the polybool
function.
maptrims No Longer Trims Edge Rows and Columns
In previous releases, you could call maptrims with an input value for latlim or lonlim
that corresponded to a parallel or meridian that ran precisely along a cell boundary.
However, when you did so, the cells adjacent to that boundary would be trimmed off
even if they fell completely within the requested limits. Now, if latlim or lonlim
corresponds to a cell boundary, the output grid extends all the way to that limit. If a
limiting parallel or meridian cuts through a column or row of input cells, the limit is
truncated to avoid partial cells.
