Gooday,

I would like some assistance in creating a code for storing multiple variables in an array when the user presses a "Pushbutton". For example when a user enters two numberic values into the application. The application then calculates the area of the room and I would like application to allow the user to store the three variables ( length_of_room, Width_of_room and Area_of_room) into and array. Any assistance is appreciated. Thank you

在 MATLAB Online 中打开

area.mlapp

Hi Kyle,

I understood you want to calculate the area from the two numeric inputs given and use it.

To do this, we can create three edit fields corresponding to length, breadth, and area of the room. An additional button is created in which the click on button will calculate the area from the length, breadth edit fields and update the area in the corresponding edit field.

In the above app, The call back of the "calculate area" button is as follows

% Button pushed function: calculateareaButton
        function calculateareaButtonPushed(app, event)
            length=app.lengthEditField.Value; % get value in length edit field
            breadth=app.breadthEditField.Value; % get value in breadth edit field
            area=length*breadth; % calculate area
            app.AreaEditField.Value=area; % update area edit field
            x=[length, breadth, area]; % store all the details in the array
        end
