Yair Altman (1 day 12 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 (12 days 15 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 (17 days 17 hours ago): Don’t reparent a pre-created uitree – create it after the new figure is already shown.
Himanshu Jain (17 days 17 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 (21 days 14 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 (23 days 12 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 (32 days 8 hours ago): Thanks for the great help

Yair Altman (47 days 18 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 (48 days 0 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 (52 days 4 hours ago): No. In the new web-based uifigures you need to use uihtml and uistyle to update the table appearance.
Santiago (52 days 4 hours ago): Hi , Yair. ¿Do the HTML options still work in the uitables created with the app designer?
Yair Altman (85 days 11 hours ago): Yes, the report is still available. You can get it here.
Luis Santiago (85 days 12 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.
