octave: The try Statement

 
 10.9 The try Statement
 ======================
 
 The original form of a ‘try’ block looks like this:
 
      try
        BODY
      catch
        CLEANUP
      end_try_catch
 
 where BODY and CLEANUP are both optional and may contain any Octave
 expressions or commands.  The statements in CLEANUP are only executed if
 an error occurs in BODY.
 
    No warnings or error messages are printed while BODY is executing.
 If an error does occur during the execution of BODY, CLEANUP can use the
 functions ‘lasterr’ or ‘lasterror’ to access the text of the message
 that would have been printed, as well as its identifier.  The
 alternative form,
 
      try
        BODY
      catch ERR
        CLEANUP
      end_try_catch
 
 will automatically store the output of ‘lasterror’ in the structure ERR.
 Errors and Warnings, for more information about the ‘lasterr’
 and ‘lasterror’ functions.
