Docking figures in compiled applications
Figures in compiled applications cannot officially be docked since R2008a, but this can be done using a simple undocumented trick.
Color selection components
Matlab has several internal color-selection components that can easily be integrated in Matlab GUI
Minimize/maximize figure window
Matlab figure windows can easily be maximized, minimized and restored using a bit of undocumented magic powder
Borderless button used for plot properties
A borderless button can be used to add unobtrusive functionality to plot axes
Datenum performance
The performance of the built-in Matlab function datenum can be significantly improved by using an undocumented internal help function
Plot-type selection components
Several built-in components enable programmatic plot-type selection in Matlab GUI - this article explains how
Blurred Matlab figure window
Matlab figure windows can be blurred using a semi-transparent overlaid window - this article explains how
Transparent Matlab figure window
Matlab figure windows can be made fully or partially transparent/translucent or blurred - this article explains how
Enable/disable entire figure window
Disabling/enabling an entire figure window is impossible with pure Matlab, but is very simple using the underlying Java. This article explains how.
An interesting uitree utility
ExploreStruct is a utility that shows how custom uitrees can be integrated in Matlab GUI
