A few parfor tips
The parfor (parallel for) loops can be made faster using a few simple tips.
MEX ctrl-c interrupt
An undocumented MEX function can help interrupt running MEX functions.
Enabling user callbacks during zoom/pan
Matlab zoom, pan and rotate3d modes hijack the user's figure callbacks, but this can be overridden.
Adding dynamic properties to graphic handles
It is easy and very useful to attach dynamic properties to Matlab graphics objects in run-time.
General-use object copy
Matlab's dual internal serialization/deserialization functions can be used to create duplicates of any object.
