Transparent uipanels
Matlab uipanels can be made transparent, for very useful effects.
Undocumented feature
uicontextmenu performance
Matlab uicontextmenus are not automatically deleted with their associated objects, leading to leaks and slow-downs.
Explicit multi-threading in Matlab part 3
Matlab performance can be improved by employing POSIX threads in C/C++ code.
Explicit multi-threading in Matlab part 2
Matlab performance can be improved by employing .Net (C#, VB, F# or C++) threads.
Undocumented button highlighting
Matlab button uicontrols can easily be highlighted by simply setting their Value property.
Accessing private object properties
Private properties of Matlab class objects can be accessed (read and write) using some undocumented techniques.
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.
Editbox data input validation
Undocumented features of Matlab editbox uicontrols enable immediate user-input data validation
Rich-contents log panel
Matlab listboxes and editboxes can be used to display rich-contents HTML-formatted strings, which is ideal for log panels.
