Stéphane Issartel (5 days 21 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 (6 days 15 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 (14 days 23 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 (15 days 5 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 (19 days 9 hours ago): No. In the new web-based uifigures you need to use uihtml and uistyle to update the table appearance.
Santiago (19 days 9 hours ago): Hi , Yair. ¿Do the HTML options still work in the uitables created with the app designer?
Yair Altman (52 days 16 hours ago): Yes, the report is still available. You can get it here.
Luis Santiago (52 days 17 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 (59 days 14 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 (59 days 20 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 (76 days 11 hours 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 (77 days 3 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 (96 days 15 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 (96 days 15 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...
