Note that this reference documentation is identical to the help that is displayed in MATLAB when you type “help peerexec”.

  PEEREXEC is the low-level function that executes the job on the
  slave. It also tries to change the path and pwd to those on the
  master and it catches and deals with any errors in the code that
  is executed.
 
  This function should not be called directly.
