18 // It is assumed that the argument passed to the constructor persists
19 // as long as the MatlabException object is in scope. Usually, this
20 // means that it should persist for the duration of the entire
21 // program. This is always the case if the input "message" is a literal.
22 //
23 // AW: Since I would like to include more detailed information (e.g.,
24 // which option is the one that is unknown), I changed this so that
25 // this object keeps a copy of the exception
