Maxima will now return -gen_laguerre(1,-3,x)/2. If orthopoly is loaded, ev(%) produces x/2+1. Is that acceptable? Or should hgfred produce the polynomial itself? In some ways, I prefer the gen_laguerre answer since you can tell that this is a special case. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=104933&aid=1858939&group_id=4933 |

It's a bit troublesome that a simplifying function returns a non-simplifying function. Maybe I'll re-visit orthopoly and consider converting all the polynomials into simplifying code. ---------------------------------------------------------------------- Comment By: Raymond Toy (rtoy) Date: 2008-01-03 11:15 Message: Logged In: YES user_id=28849 Originator: NO The immediate problem with gamma(-2) being undefined has been fixed.
