Sunham (3 days 5 hours ago): This is an old article, but the issue persists even in 2023. 2023a: z = mat2cell(1:1e6,1,repmat(1,1,1e 6)); f = @() cellfun(‘isempty’, z); g = @() cellfun(@isempty,z);...
Yair Altman (12 days 19 hours ago): Robot only runs when you tell it to run a command such as keyPress. If you don’t tell it to run a command, it uses no CPU, so there’s no need to remove the Robot...

Nicholas (28 days 17 hours ago): Yair, Changing the desktop help options did not solve the issue. Though, it’s unclear how I could change these options in the Runtime, if that’s what you meant? I should...
Yair Altman (32 days 12 hours ago): @Francisco – this is one of those cases where you should ask MathWorks support. After all, you’re trying to use a supported Matlab functionality when you encountered...
Francisco Campos (33 days 0 hours ago): Hello, thanks for all your work that has been immensely useful for those working in the Matlab environment. I have been trying to replace matlabcontrol with the official...
