- Memory leaked by any mex files is cleaned up (mxMalloc... or MATLAB arrays). The best practice is to only rely on automatic clean up in the event of an error.
- Any pending display/graphics messages are processed by MATLAB. This can be forced by adding a drawnow to your code. In general this should not cause an issue because there should not be a huge number of events pending but there have been bugs in the distant past.
What happens on Ctrl + C?
