[sympy] interpretting output involving a hypergeometric function

2013-03-31 Thread Ben Goodrich
Hi, When I input y = symbols("y", positive=True) z = symbols("z", real=True) K = symbols("K", integer=True, positive=True) eta = Symbol("eta", positive=True) g = y * ((1-(z*y)**2)**(-2+K/2 + eta) * gamma(S(1)/2 * (-1+K)+eta))/(sqrt(pi) * gamma(-1+K/2+eta)) * (2 * (y**2)**eta (1-y**2)**(S(1)/2 *

Hello everyone, I am a computer science student interested in mathematics. I have gone through the SymPy documentation under statistics section and found some distributions and test missing, e.g. Chi-Square test, Poisson distribution, Binomial distribution to name a few. As I am relativel

>From the little you have explained about "k" I would guess that you can evaluate them for any "x". Just do it that way. At no point is there a requirement in the packages that you are using for a grid of fixed "x"es. You seem to be confused about what interpolation does. See http://en.wikipedia.or

Thank you Stefan, I will follow your advices. I tried to solve this problem through scikits.bvp_solver (e.x. http://pythonhosted.org/scikits.bvp_solver/examples/examples.example5.html ) cause the second B.C of u' is not initial at x=0 but at x=N(x max). But there I had the same problem, how

You should address your questions about scipy and numerics to the scipy mailing list (the sympy mailing list has a different focus). I do not understand all of your questions but nonetheless: - the interpolated "k"s are just functions. You can call them from inside the function representing the de

Stefan, I manage to figure out how the k1_func() works. I have two more questions if I may; 1. how to use k*_func inside the def" my_first_derivative" ? DO I need to write as k1_func(x) ? 2. theoretically, this problem should be solved through Newton iteration method, cause is a 2 boundary

I usually do a rebase or a PR when a merge conflict occurs. To do this first fetch the latest upstream master with git fetch origin (make sure that origin points to the upstream sympy repo and not to your sympy repo on github.) then do git rebase origin/master In the case of a merge conflict dur
