Comment #11 on issue 4133 by raou...@gmail.com: Suggestion: implement
classical orthogonal polynomials
http://code.google.com/p/sympy/issues/detail?id=4133
Try to make f.e. the Hermite polynomial non-autoevaluating for
any (numeric as well as symbolic) n and x.
I described what you need to do in a previous mail:
- cut out the code in eval(...) of the Hermite class
- put it into another suitable member function of the same class.
(A first and usually good candidate would be "_eval_expand_func(...)")
You can get a guide by looking into the solution
implemented for spherical harmonics.
If you have more questions, feel free to ask me. Probably I'll
have more time next week to help you if necessary.
