check if user stops script in matlab

One way to check if the user stops the script in MATLAB is to use a try-catch block in your code that catches the MException thrown by the ctrl-c signal. Here's an example:

main.m
try
    % your code here
catch ME
    if strcmp(ME.identifier, 'MATLAB:Interrupted') 
        disp('User stopped the script.')
    else
        % handle other exceptions
    end
end

The code inside the try block will be executed normally until the user presses ctrl-c. When that happens, the catch block will catch the MException with identifier MATLAB:Interrupted, which indicates that the script was interrupted by the user. You can then handle this case as needed, for example by displaying an error message or cleaning up any resources.
