GUI Edit Boxes and recalling values.

Hi there,

I have just started to make a GUI for a Shooting method projectile problem.

I have 2 input angles and a error specified by the user. I have 3 edit boxes where I input the data for the three values (theta1, theta2, reqe). Please see code below.

function theta2_Callback(hObject, eventdata, handles)
% hObject    handle to theta2 (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)

% Hints: get(hObject,'String') returns contents of theta2 as text
%        str2double(get(hObject,'String')) returns contents of theta2 as a double
theta2 = str2double(get(hObject,'string'));
if isnan(theta2)
  errordlg('You must enter a numeric value','Bad Input','modal')
  uicontrol(hObject)
  return
end

same thing for theta 1 and reqe.

Then I have a push button where I want to run my function file called 'Shooter'

But I can't seem to do it. Also i cannot carry forward the variables from the previous functions. The Shooter function needs all 3 values to run.

Shooter(theta1, theta2, reqe);

This m file then calculates everything I need.

Many thanks.

Thank you for your reply. Unfortunately I didn't really understand what is was trying to get across.

It's ok I figured it out using the handle method. Thanks
