how to use similar push button in a loop for saving numbers from edit box in matlab GUI

Hi,

I am new at matlab GUI. Actually I have to take multiple input values from a edit box in such a way that when ever I press the push button it takes the value from edit box and save into first coulumn of an array now when I put other num in the same editbox and push pushbutton it will save that value into second column of the same array and so far it will continue untill I use other push button to save the whole array. Can any body help me how can I do that.

When a callback function in invoked, all of the variables within the callback function are created in its own workspace. When the function completes, all of those variables go away forever unless you save them somewhere. So every time you press the pushbutton, you need to store the current value as a vector that you save somewhere. A common solution is to store data within the "UserData" property of some graphics object within your GUI.

Here's an example that stores the vector within the UserData property of the numeric text field.

 function ButtonPushed(app, event)
    % store new value at the end of the vector
   aap.EditField.UserData(end+1) = app.EditField.Value; 
   % reset the edit field back to it's default value (if needed)
   app.EditField.Value = 0; 
 end

You can clear the vector from memory like this

 aap.EditField.UserData = []; % reset vector
