How to force a matlab script to rerun the script from the beginning using list items and if statement?

Helly everyone,

I have the following code:

% Here is the Main Code that does stuff

% After the code has done some stuff the user is left with three options:

list = {'text1','text2','RERUN_SCRIPT'};
[indx] = listdlg('SelectionMode','single','ListString',list);

% with the following if statements

if indx == 1
    % code for importing works
end

if indx == 2
    % code for deleting unwanted external files work
end

if indx == 3
    % I cannot find a direct method to start the script again. 
end

Also there is one problem: While my list is active I cannot edit my figure in the main code. Is there an option, even by default, allow an active edit of figures, etc. while list is active?

Scripts execute from top to bottom. MATLAB does not have a GOTO command. However, you can accomplish this by reorganzing your code. For example, consider putting all the code you want to rerun inside a while loop, and repeat that loop as long indx==3.

indx == 3
while indx == 3
    % After the code has done some stuff the user is left with three options:
    
    list = {'text1','text2','RERUN_SCRIPT'};
    [indx] = listdlg('SelectionMode','single','ListString',list);
    
    % Use a switch statement. The loop will continue execution as long as the user selects 'rerun'    
    switch indx
        case 1
        % code for importing works
        case 2
        % code for deleting unwanted external files work
    end
end

I will try this out.

Ok everythink works perfectly. I thought there was a GOTO function but this is also convenient solution. I just have a few more quesitons:

1.) If I were to expand this list with more than three elements, do I have to change the indx variable, appearing above the while loop code, to the last index number?

2.) The case command is nothing more than a representation of the first until the pre last index number. right?

3.) Is it possible to edit e.g a figure while the list options are present? Matlab denies any interaction with the figure (like zoom in and out)

For 1 and 2, I suggest learning more about how switch statements work. You define cases, and use the switch to set which case executes. If no case matches the switch, nothing is executed.

For 3, I'm not sure. I'm comfortable saying that when a user dialog is displayed, it is given focus. There may be a way to override this, but it's not something I have experience with. I'd suggest posting that as its own question and seeing if anyone else can help.

Ok will take a look at the switch statements in general in isolate the 3rd question as a new one.
