How can I implement a dialog GUI in MATLAB?

task_complete=0;
while task_complete==0
    disp(' ')
    disp('1:Q1')
    disp('2:Q2')

      P_Switch = input ('Enter Question Number:');
      switch P_Switch
          case 1
              clear
              disp('solve Q1')
              P1
          case 2
              clear
              disp('solve Q2')
              P2
      end
      disp('  ')
      task_complete=input(' Correct Solution? yes=1, no=0:');
  end

Can I get this to be a dialog box with eye candy buttons instead of text?

Yes you can, how?

1-create a figure
2-create two buttons
3-create text box for the questions and info
4-create edit box for the input
5-add your code

Using GUIDE that's super easy, doing it without GUIDE is only a little harder.

See questdlg()

Answer 3

[Matt Fig]

Something like this:

task_complete='No';
while strcmp(task_complete,'No')
    C = questdlg('Choose question to solve:', ...
                 'Select a question', ...
                 '1','2','1');
    switch C
        case '1'
            P1
        case '2'
            P2
    end
    task_complete = questdlg('Are we done?', ...
                             'Finished?', ...
                             'Yes','No','Yes');
end

[Walter Roberson]

Matt's solution closely follows the logic of the original question. Neither the original question nor Matt's solution will explicitly recognize that some other value than 1 or 2 has been chosen, a chase that _probably_ should not ask the 'Done' question but should instead go back to asking the question again.

The way to recognize other data as having been entered is to use a default section in the switch statement.

(Specifically, if the user clicks on the Close button or on the Cancel button, the result of questdlg() will be the empty string. The default value that Matt provided, the '1', is used only if the user presses Return.)

[Matt Fig]

Yes, I recognized that too. It will be up to buxZED to define the behavior of the program in case the user opts out at the dlg. Does it quit? Does it keep pestering with a dialog? Only buxZED knows...
