When I use the command
set(aaa.uic3(:),'handlevisibility','callback')
the error message appears:
Error using matlab.graphics.Graphics/set
The name 'handlevisibility' is not an accessible property for an instance of class 'matlab.graphics.GraphicsPlaceholder'.
Any ideas what is wrong?

Victor - what object types do the handles in the aaa.uic3 array correspond to? Perhaps at least one does not have the HandleVisibility property?

Similar to how
a(3) = true
fills a(1) and a(2) with false, your SkMp.uic3 (which is a 4x9 Graphics array) fills empty values with GraphicsPlaceholder objects. One option is to store your graphics objects some other way, like with a cell array, to avoid allocating space that you don't need and don't use.
Another option is to loop through the array and check whether 'HandleVisibility' is a property of each element:
for i = 1:numel(SkMp.uic3)
if isprop(SkMp.uic3(i), 'HandleVisibility')
set(SkMp.uic3(i),'handlevisibility','callback')
end
end

valobj = findobj(SkMp.uic3(:), 'flat', '-property', 'handlevisibility');
set(valobj, 'handlevisibility', 'callback')
