title: How to Stop a MATLAB Timer Object From The Function's Workspace After It's Executed
body: <p>Say I've got a function that evaluates to:</p>
  
  <pre><code>function test_timer()
  a = timer ;
  set(a, 'executionMode', 'fixedRate','TimerFcn','disp(rand)')
  start(a)
  
  end
  </code></pre>
  
  <p>..and I've accidentally left out 'stop(a)' within the function's clause. 
  How do you stop the timer object (or all timer objects) from running without closing MATLAB using the command window?</p>
