uicontextmenu performance
Matlab uicontextmenus are not automatically deleted with their associated objects, leading to leaks and slow-downs.
Handle graphics
Serializing/deserializing Matlab data
Matlab does not provide a documented manner to serialize data into a byte stream, but we can do this with some undocumented functionality.
Performance: accessing handle properties
Handle object property access (get/set) performance can be significantly improved using dot-notation.
Draggable plot data-tips
Matlab's standard plot data-tips can be customized to enable dragging, without being limitted to be adjacent to their data-point.
Waterloo graphics animation and web deployment
Waterloo graphics can be updated very quickly in Matlab, enabling plot animation; web deployment of the graphics is also possible.
Waterloo graphics beta
The Waterloo graphics library extends Matlab graphics with numerous customizable plots that can be embedded in Matlab figures.
HG2 update
HG2 appears to be nearing release. It is now a stable mature system.
ishghandle's undocumented input parameter
The built-in function ishghandle accepts a second input argument with the expected handle type.
HG's undocumented parameters interface
Some HG functions also accept inputs parameters in a struct fields rather than the normal P-V pairs format.
