giving the option of restarting the code in matlab

To give the option of restarting the code in MATLAB you can use a loop structure. Here is an example:

main.m
choice = 'Y';
while upper(choice) == 'Y'
    % Your code here
    % ...

    % Ask user if they want to restart
    choice = input('Do you want to restart? Y/N: ', 's');
end

9 lines

The while loop will continue executing until the user enters 'N' or any other input that is not 'Y'. The input function is used to prompt the user for input, and the 's' argument specifies that it should be read as a string. The upper function is used to convert the input to uppercase so that both 'Y' and 'y' will be accepted.
