Blocked wait with timeout for asynchronous events
It is easy to convert asynchronous (streaming) events into a blocked wait in Matlab.
Memory
Quirks with parfor vs. for
Parallelizing loops with Matlab's parfor might generate unexpected results. Users beware!
General-use object copy
Matlab's dual internal serialization/deserialization functions can be used to create duplicates of any object.
New book: Accelerating MATLAB Performance
Accelerating MATLAB Performance (ISBN 9781482211290) is a book dedicated to improving Matlab performance (speed).
Allocation performance take 2
The clear function has some non-trivial effects on Matlab performance.
File deletion memory leaks, performance
Matlab's delete function leaks memory and is also slower than the equivalent Java function.
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.
