Tips for accelerating Matlab performance

I’m proud to report that MathWorks has recently posted my article “Tips for Accelerating MATLAB Performance” in their latest newsletter digest (September 2017). This article is an updated and expanded version of my post about consulting work that I did for the Crustal Dynamics Research Group at Harvard University, where I helped speed-up a complex Matlab-based GUI by a factor of 50-500 (depending on the specific feature). You can read the full detailed technical article here.

Featuring an article on the official newsletter by a non-MathWorker is rare. Doing this with someone like myself who has a reputation for undocumented aspects, and a consultancy business that potentially competes with theirs, is certainly not obvious. I take this to be a sign that despite the possible drawbacks of publishing my article, MathWorks felt that it provided enough value to the Matlab user community to merit the risk. I applaud MathWorks for this, and thank them for the opportunity of being featured in their official newsletter and conferences. I do not take it for granted in the least.
The newsletter article provides multiple ideas of improving the run-time performance for file I/O and graphics. Many additional techniques for improving Matlab’s performance can be found under the Performance tag in this blog, as well as in my book “Accelerating MATLAB Performance” (CRC Press, 2014, ISBN 978-1482211290).

I am offering a couple of webinars about various ways to improve Matlab’s run-time performance:

Matlab performance tuning part 1 (3:39 hours, syllabus) – $195 (buy)
Matlab performance tuning part 2 (3:43 hours, syllabus) – $195 (buy)
==> or buy both Matlab performance tuning webinars for only $345 (buy)

Both the webinar videos and their corresponding slide-decks are available for download. The webinars content is based on onsite training courses that I presented at multiple client locations (details).
Email me if you would like additional information on the webinars or my consulting, or to inquire regarding an onsite training course.

Yair,

Excellent advice as always.

I’m attempting to incorporate a breadcrumb bar into a GUI. After failing to get JIDE’s (com.jidesoft.navigation.BreadcrumbBar) to work, I tried Mathwork’s Addressbar…

Which seems to look and function correctly. I just cannot figure out how to get the dataChangeNotifiction callbacks in Matlab.
Do you have any suggestions?

Sincerly

Collin

@Collin – I’ll be happy to assist you by spending time to investigate this for you, but I would naturally expect to be compensated for my time and expertise. Email me (altmany at gmail) if you’re interested.

Yair Altman (5 days 5 hours ago): Yes, the report is still available. You can get it here.
Luis Santiago (5 days 7 hours ago): Hi Yair. Your articles are excellent and, even now, they are still applicable. Is the uitable report still available? I’d really like getting it.
Adam D Danz (12 days 3 hours ago): Opps…. I was using the wrong syntax: MarkedClean is an EventName and I was accidentally treating it as a PropertyName. Also, ignore the “MarkedDirty” reference...
Adam D Danz (12 days 4 hours ago): Yair, thanks for your unmatched contributions to exploring Matlab under the hood. I noticed that listeners responding to MarkedClean in geoaxes throw an error even though...
Adee Ran (12 days 10 hours ago): Yair, once again, I find the answer to the issue that annoy me is in your site since long ago. Both the highlighting control and focus control (using uicontrol() ) are simple,...
Yair Altman (29 days 1 hour ago): @Tucker – AFAIK markedClean still works even in the very latest release. In recent years MathWorks added a few documented hooks for trapping axes updates etc., but the...
Tucker Downs (29 days 17 hours ago): Hi Yair, Is “markedClean” still your recommendation for wanting to redraw graphics primitive like objects? I’m working on trying to make some native-like...
Yair Altman (49 days 5 hours ago): It is not clear from your comment what command you’re trying to use. You basically have 4 alternatives: To use the builtin saveas function To use the builtin...
Alvaro (49 days 5 hours ago): Hello all, First of all let me thank you for your posts they were very helpful. I implemented a code to show contour labels with scientific notation in latex format...
Yair Altman (54 days 10 hours ago): Perhaps the uihtml function can help you (R2019b or newer). In any case, uifiures use a radically different underlying technology than Java-based figures, so everything...
Neelakanda Bharathiraja (54 days 10 hours ago): Hi Yair, Please let us know how to create the same integrated browser control with uifigure.
matt (63 days 21 hours ago): There is no Edge in quiver, so this workaround will not help.
matt (63 days 21 hours ago): I very much wanted this to work with Quiver, and it does as long as the number of points is not too big. Using 2018a, I get the warnings/errors above even if placed in a single call to...
matse (69 days 5 hours ago): Is there a possibility to rotate the controllib.widget.Slider? So to have it vertical? Thanks!
Yair Altman (74 days 8 hours ago): Perhaps it’s because the table is empty, I don’t know. In any case, I think you can ignore this error, I don’t think that it affects the functionality.
