Fixing Matlab's actxserver
Matlab's COM (ActiveX) server behavior can be fixed in a couple of useful manners.
Low risk of breaking in future versions
Removing user preferences from deployed apps
An unsupported MathWorks Technical Solution explains how to remove private information from deployed (compiled) matlab applications.
Buggy Profiler option
a bug exists in the profiler that prevents usage of its documented CPU timing functionality.
Images in Matlab uicontrols & labels
Images can be added to Matlab controls and labels in a variety of manners, documented and undocumented.
Changes in the online doc URLs
Matlab release R2012b has broken a vast number of links to its online documentation pages.
Matlab installation take 2
A list of suggested config changes to the default Matlab installation is detailed.
File deletion memory leaks, performance
Matlab's delete function leaks memory and is also slower than the equivalent Java function.
Pause for the better
Java's thread sleep() function is much more accurate than Matlab's pause() function.
Speeding up compiled apps startup
The MCR_CACHE_ROOT environment variable can reportedly help to speed-up deployed Matlab executables.
ScreenCapture utility
The ScreenCapture utility uses purely-documented Matlab for capturing a screen region as an image from within Matlab.
