Run a function with input arguments using App Designer

Question

0 个投票

I have a MATLAB script file (.m file) which is a function

%It begins like this
function M = qcldpc(j, k, a, b, p)

I am trying to create an application that can run multiple of such .m files using app designer.

I want to get the input parameters from the user to be run in the function file. How do I do this. I am brand new to app designer and would love some pointers. Thank You

If you do the few examples that are available in App Designer, you'll get an idea what do you need to do.

Yeah, I got it thanks. Now I have another trouble.

%This function uses a script qcldpc to calculate 2 outputs that I need to be using in another function...
function CreateButtonPushed(app, event)
            j = app.RowjEditField.Value;
            k = app.ColumnkEditField.Value;
            a = app.oaEditField.Value;
            b = app.obEditField.Value;
            p = app.SizeofIxEditField.Value;
            [B,M] = eval('qcldpc(j, k, a, b, p)');
            app.UITable.Data = B;
          
        end

I need to use the output I got using eval in this to the next function

        function SimulateButtonPushed(app, event)
            db = app.SNRLimitEditField.Value;
            it = app.IterationsEditField.Value;
            msg = eval('Final(M,db, it)');
        end

But there is an error message displaying saying that

      %Error using eval
      %Unrecognized function or variable 'M'.

I figured out that it had something to do with the Public property thingy. Can you point me out to the right method to do this? Thanks in advance.

Great work, thank you for doing those.

You can set your variables into the property of the app and you'll be able to use those in other callbacks, functions etc. Public properties allow access to their values outside of app, private do not.

% Verify if properties block is correctly written
properties (Access = private)
    M
end
function CreateButtonPushed(app, event)
    j = app.RowjEditField.Value;
    k = app.ColumnkEditField.Value;
    a = app.oaEditField.Value;
    b = app.obEditField.Value;
    p = app.SizeofIxEditField.Value;
    [B, app.M] =qcldpc(j, k, a, b, p);
    app.UITable.Data = B;      
end
function SimulateButtonPushed(app, event)
    db = app.SNRLimitEditField.Value;
    it = app.IterationsEditField.Value;
    msg = Final(M,db, it);
end

Wow, that was straightforward and simple. I have been complicating things. Thanks a ton.

Also, a warm reminder from all of us here, don't use eval. Have a great day.
