title: modify precision of a decision tree in MATLAB
body: <p>I created a regression tree using fitrtree
  I want to take parameters such as CutPoint and reduce the precision, something like this:</p>
  
  <pre><code>tree.CutPoint=round(tree.CutPoint,5);
  </code></pre>
  
  <p>but I cannot do this because CutPoint is set as read only, I want to either modify it or create a tree that is essentially the same as this one but with those modifications. Unfortunately, documentation only show constructors trough the fitrtree function. Is it possible to do this? and if so, how?</p>
