- Jim Hokanson (3 hours 17 minutes ago): Incredible.
- Shuhao Cao (8 hours 55 minutes ago): Haha, I see. Thanks a lot. I have looked into it but found no ‘MenuFont’. Guess there is no easy workaround within...
- Yair Altman (9 hours 1 minute ago): Of course – simply open the preferences file in a text editor edit([prefdir '/matlab.prf'])
- Shuhao Cao (9 hours 3 minutes ago): Thanks for the quick reply. Is there a way to see what are all the relevant preference names?
- Yair Altman (9 hours 21 minutes ago): @Shuhao – after modifying the prefs you need to restart Matlab. You need to ensure (of course) that the relevant...
- Shuhao Cao (9 hours 34 minutes ago): Hi, Yair Your website is so helpful! I followed some of the matlab customization on your website, now I wonder if I could change...

Profiling Matlab memory usage
mtic and mtoc were a couple of undocumented features that enabled users of past Matlab releases to easily profile memory usage.
Matlab mex in-place editing
Editing Matlab arrays in-place can be an important technique for optimizing calculations. This article shows how to do it using Mex.
Matlab-Java memory leaks, performance
Internal fields of Java objects may leak memory – this article explains how to avoid this without sacrificing performance.

Performance: scatter vs. line
In many circumstances, the line function can generate visually-identical plots as the scatter function, much faster
