This is an internal error. Though this expression does not have a Taylor/Laurent expansion, it should still give a user-oriented error, not an internal error. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=104933&aid=658850&group_id=4933 |
