Undocumented Profiler options part 2
Several undocumented features of the Matlab Profiler can make it much more useful - part 2 of series.
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.
Splash window for deployed applications
Deployed (compiled) Matlab applications take a long time to load. I present a splash window that loads immadiately, solving this problem.

Waiting for asynchronous events
The Matlab waitfor function can be used to wait for asynchronous Java/ActiveX events, as well as with timeouts.
Trapping warnings efficiently
warnings can be trapped in a try-catch block just like regular errors. This articles explains how.
Internal Matlab memory optimizations
Copy-on-write and in-place data manipulations are very useful Matlab performance improvement techniques.
