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