#MEDFILT2 MATLAB 2012 UPDATE#

Update 8th March 2010: Added new functions that became multicore aware in version 2010a.

#MEDFILT2 MATLAB 2012 PLUS#

Update 16th June 2011: Added new functions that became multicore aware in version 2011a plus a couple that have been multicore for a while but I just didn’t know about them! Not sure when they became multithreaded so left the version number blank for now Update 18th February 2012: Added a few functions that I had missed earlier: erfcinv, rank,isfinite,lu and schur. pinv makes use of svd which is probably the bit that’s multithreaded. Update 11th May 2012 While optimising a user’s application, I discovered that the pinv function makes use of multicore processors so I’ve added it to the list. Of course when I came to write all of this up I did some googling and discovered that The Mathworks have already answered this question themselves! Oh well….I’ll publish my list anyway. I am almost certainly missing some functions and details so if you know something that I don’t then please drop me a comment and I’ll add it to the list. If there is any extra detail then I have included it in brackets (typically things like – ‘this function is only run in parallel for input arrays of more than 20,000 elements’). On a recent train journey I trawled through all of the release notes in MATLAB and did my best to come up with a definitive list and the result is below.Īlongside each function is the version of MATLAB where it first became parallelised (if known).

So, for certain functions you will see a speed increase in your code when you move to a dual or quad core machine. Slowly but surely, The Mathworks are parallelising some of the built in MATLAB functions to make use of modern multicore processors. Wouldn’t it be nice if you could do no work at all and yet STILL get a speedup on a multicore machine? Well, you can….sometimes.
