Compatibility Considerations
Before R2010a, the mlayers and mobjects GUIs had an EraseMode option, which
made it possible to set the erase mode on a particular map layer or object. This property
controlled the technique MATLAB used to draw and erase hggroup child objects.
scatterm Now Returns a Handle to an hggroup Object
The function scatterm in the syntax
h = scatterm(...)
now returns a handle to an hggroup.
Compatibility Considerations
In previous releases, scatterm returned a vector of patch handles.
mdistort Now Returns a Handle to a contourgroup Object
The output of the syntax
h = mdistort(...)
is now a scalar handle to a contourgroup object containing the contours and text.
Compatibility Considerations
In previous releases, mdistort returned handles to the line and text objects and used the
syntax
[h,ht] = mdistort(...)
with two output arguments. The second output of mdistort is now redundant because
these handles will be available as children of h.
polybool No Longer Errors when Given Empty Input Vertex Arrays
When one or both pairs of input vertex arrays is empty, the polybool function now
returns either empty values or the values of the non-empty input pair, depending on the
requested operation.
For example, consider the following case:
