Preallocation performance
Preallocation is a standard Matlab speedup technique. Still, it has several undocumented aspects.
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.
