Changing this to check for listp before doing caar fixes the immediate issue. However, the result is then product-of-y-with-nofract-indices. I'm not sure under what conditions fractest is supposed to work for Bessel Y functions. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=104933&aid=1753971&group_id=4933 |
