Hi,
I also implemented Catalan numbers recently but never pushed my branch to github till now. You can find it at: http://github.com/raoulb/sympy/tree/catalan_numbers Maybe I could merge your patch in and later send a pull request. BTW, I used a slightly different formula allowing (in principle) even complex numbers n as input. But I'm not sure if this extension was done somewhere in the math literature. Do you also have any tests and doctests for your patch? If no this is not a problem as I wrote some. -- Raoul -- You received this message because you are subscribed to the Google Groups "sympy" group.
