Controlling plot data-tips
Data-tips are an extremely useful plotting tool that can easily be controlled programmatically.
Minimize/maximize figure window
Matlab figure windows can easily be maximized, minimized and restored using a bit of undocumented magic powder
Datenum performance
The performance of the built-in Matlab function datenum can be significantly improved by using an undocumented internal help function
