Yair Altman (3 hours 46 minutes ago): Starting in R2022b the legacy @ syntax has changed from a warning to an error. Classes that use the legacy syntax generate a run-time error and no longer run.
Jeremiah Sullivan (4 hours 48 minutes ago): For what its worth, I am still getting that same “undocumented syntax” warning in 2022a. I really hope they don’t create another breaking change…
SKM (21 days 22 hours ago): It is 10 years since the original article, but I would like to bring to attention that such issues have not yet been resolved. For example, programmatically opening and closing files in...
Yair Altman (52 days 8 hours ago): @Ken – I cannot reproduce your report, it works as expected for me even on R2022b
Yair Altman (52 days 11 hours ago): try to use the waitfor function
Danila Berezin (56 days 23 hours ago): Hi I have a similar issue. Did you find a workaround for this?
Ken Johnson (65 days 12 hours ago): Why does the second catch block in this code example not work? (It works if you restart MATLAB and then omit the first try-catch block.) try a = [0,0;0,0]\[1;1]; catch...
Santiago (70 days 2 hours ago): It works perfectly. Thanks so much.
Yair Altman (70 days 8 hours ago): Santiago – you can get the mouse X,Y positions from the Java eventData object (getX(), getY()), convert this into a point (p=java.awt.Point(x,y)), then use the JTable...
Santiago (71 days 0 hours ago): Hi Yair. I’m using the MouseReleasedCallback but I need to get the indices of the selected cell. I can get them without problems with left clicks but, if I try to do it with...
Yair Altman (89 days 4 hours ago): Adam – perhaps there is a builtin syntax-pane control for uifigures, but I am not aware of one. Perhaps you can try to implement a uihtml panel with a GeSHi...
Yair Altman (89 days 4 hours ago): Marcel – 12 years and ~25 releases since I wrote this article, it is no surprise at all that some things no longer work the same way. In fact, the surprising thing is that...
Yair Altman (89 days 4 hours ago): See the documentation of the uitree function. The text in my article refers to the legacy (Java-based) uitree version, which is not documented, whereas it is documented and...
SOULEYMANE Zakaria (94 days 9 hours ago): Hello. Thank you for sharing. I would like to know if someone could help me with the syntax it takes to use uitree on “Appdesigner”. When I use the syntax you...
Nicholas (94 days 21 hours ago): Hello Yair, Have you, or anyone else, had an opportunity to try this demo in R2022a/b? I cannot get the HTMLBrowserPanel object to update with html text (nor with an html file, if...
