How do I delete some tabs in a tab group in AppDesigner programatically?
Steps I am currently doing:
1. I am plotting a bar by a push button.
2. Expectation: When I am re-pushing the push button I want the old tabs to be deleted and new ones to come up.
Current: When I am re-pushing the push button, the old tabs are staying and fresh set of new tabs are opening.

Hi Partha Mitra,
You can use the delete method to remove the old tabs and plot the new bar in a fresh tab.

Hi, can you give an example of this please?
This does not work:
If you use this method to create the tabs in the first place:
I'm probably missing something, so an example would be great.
Specifically, if you create an "app property" to hold handles to UI elements, how do you "delete" them? "clearing" or setting to empty does not remove the element obviously.
For instance:
properties (Access = private)
tabs % structure to hold the tabs for different datasets
end
and creating like this:
app.tabs=cell(1,length(dataSets));
then:
for i=1:length(dataSets)
app.tabs{i}= uitab(app.TabGroup,"Title",['Measurement ' num2str(i)]);
end

Actually... is it just OK to "copy" the handle to a local variable and delete it? It seems to work, but is it "clean"?
for i=1:length(app.tabs)
a=app.tabs{i};
delete(a);
end
for instance?
