Quirks with parfor vs. for
Parallelizing loops with Matlab's parfor might generate unexpected results. Users beware!
Memory
Assessing Java object size in Matlab
Java object sizes are not reported by Matlab, but we can still estimate them using two free external utilities.
Allocation performance take 2
The clear function has some non-trivial effects on Matlab performance.
The Java import directive
The import function can be used to clarify Java code used in Matlab.
Internal Matlab memory optimizations
Copy-on-write and in-place data manipulations are very useful Matlab performance improvement techniques.
Array resizing performance
Several alternatives are explored for dynamic array growth performance in Matlab loops.
Preallocation performance
Preallocation is a standard Matlab speedup technique. Still, it has several undocumented aspects.
Matlab's internal memory representation
Matlab's internal memory structure is explored and discussed.
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.
