title: How can I save the edit box data in the GUI Guide?
body: <p>I am making a GUI in which there is a multi-line edit box.</p>
  
  <p>the user will have to input the 3 x-y coordinates in this edit box at a time:</p>
  
  <pre><code>[345.567 123.123] 
  [390.567 178.098]
  [378.000 125.987]
  </code></pre>
  
  <p>by clicking the push button I want these coordinates to be <strong>"saved"</strong> in the Matlab GUI workspace in the form of a <em>matrix</em> and by clicking another push button <strong>"reloaded"</strong> from the workspace so that they can be available for future use.</p>
  
  <p>How can I do that?</p>
  
  <p>Can anyone guide me with this? Help would be appreciated!</p>
