Hi,

I was working on the app designer in matlab which has 3 buttons. For the first two buttons it prints the entrance time and exit time as sprint variables which are extracted from the clock function once the button is clicked. I want to use the two variables when the clock function is used to subtract them when the third button is clicked.

        %Button1 button pushed function
        function Button1ButtonPushed(app)
            A1 = clock;
            fix(A1)
            E1 = sprintf('\n%2.0f:%2.0f:%2.0f',A1(4),A1(5),A1(6));
            app.Enter1.Value = E1;          
        end
        % Button2 button pushed function
        function Button2ButtonPushed(app)
            B1 = clock;
            fix(B1)
            S1 = sprintf('\n%2.0f:%2.0f:%2.0f',B1(4),B1(5),B1(6));
            app.Exit1.Value = S1;
        end
        % Button3 button pushed function
        function Button3ButtonPushed(app)
            T = etime(B1,A1);
       end

在 MATLAB Online 中打开

app should be an object of a class so it has properties. You can add your own properties and then you have access to these anywhere where you have the app available.

e.g.
