Comment #12 on issue 4133 by [email protected]: Suggestion: implement classical orthogonal polynomials
http://code.google.com/p/sympy/issues/detail?id=4133

Ok. I have started work on this. The current eval in the default case is getting a pass instead of the poly eval. I will add a new method for conversion to monomial expansions.

I'm not sure that jacobi and gegenbauer polynomials should automatically convert to other types when the parameters correspond to legendre and chebyshev etc.

I will also write a dictionary for numerical evaluation. NumPy doesn't implement chebyshev of the second kind, gegenbauer or jacobi, but I will write a routine for these.

Furthermore, I would suggest new classes for polynomial series, which could be converted from one type to another.

Should I create a new fork for this?
