Array resizing performance
Several alternatives are explored for dynamic array growth performance in Matlab loops.
Stock Matlab function
Preallocation performance
Preallocation is a standard Matlab speedup technique. Still, it has several undocumented aspects.
Spy Easter egg take 2
The default spy Easter-egg image in the spy function has recently changed.
Expanding urlread capabilities
The built-in urlread functions has severe limitations. This article explains how to solve them.
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.
MLintFailureFiles or: Why can't I save my m-file?!
Sometimes Matlab gets into a state where it cannot use a valid m-file. This article explains what can be done.
Matlab-Java memory leaks, performance
Internal fields of Java objects may leak memory - this article explains how to avoid this without sacrificing performance.
Command Window text manipulation
Special control characters can be used to format text output in Matlab's Command Window.
Determining axes zoom state
The information of whether or not an axes is zoomed or panned can easily be inferred from an internal undocumented object.
