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 (22 days 0 hours ago): Try to use a filename with .gz extension – this will use GZIPOutputStream instead of ZipOutputStream to compress the data, and perhaps it will solve the problem. If not,...
Thomas (33 days 3 hours ago): Thanks Yair, and sorry I’ve not been warned of your answer. I’m facing again the issue, even when increasing this Matlab setting to its maximum (8,159Mb). I guess the...
Yair Altman (38 days 5 hours ago): Don’t reparent a pre-created uitree – create it after the new figure is already shown.
Himanshu Jain (38 days 6 hours ago): My uitree is already created but it’s visibility is set false. Now I created new figure and I want to attach the already created uitree to this figure. I tried setting...
Yair Altman (42 days 2 hours ago): I don’t recommend using Matlab’s GUIDE – it is being replaced with appdesigner in recent releases, and in a few releases GUIDE will no longer be available. In...
Santiago (44 days 0 hours ago): Hi, Yahir. Your work here is excellent and very helpful for all of us. I have a doubt, is it possible to create a kind of “traffic light” in the Matlab Guide? I want to...
Nitin (52 days 20 hours ago): Thanks for the great help
Stéphane Issartel (59 days 4 hours ago): Both .mlx and .mlapp file format seem to be “Open Packaging Conventions” formatted files. See https://en.wikipedia.org/wiki/ Open_Packaging_Conventions#...
Cris Luengo (59 days 22 hours ago): Neither set(0,’HideUndocumented’,’off’ ) nor classhandle(…) work any more (testing on R2021a). However, it is possible to convert a HG2 handle to a struct, and see all the...
Yair Altman (68 days 6 hours ago): yes – assuming you created the spinner using the javacomponent function, you can modify the Position and Units properties of the component’s container handle, which...
Santiago (68 days 12 hours ago): Hi Yair. Is it possible to modify the spinner’s position (x, y, w, h) after it has been created? I’m trying to do it during a SizeChangedFcn callback. Thanks.
Yair Altman (72 days 16 hours ago): No. In the new web-based uifigures you need to use uihtml and uistyle to update the table appearance.
Santiago (72 days 16 hours ago): Hi , Yair. ¿Do the HTML options still work in the uitables created with the app designer?
Yair Altman (105 days 23 hours ago): Yes, the report is still available. You can get it here.
Luis Santiago (106 days 0 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.
