Hi Sympy group, many of you are obviously reading the scipy mailing list ... So I just wanted to hear your comments on the posting below: I looked up the home page of NZMATH and was wondering how it compares to sympy ? Obviously their stuff about rational numbers and polynomials exists in sympy, so how about the factorization part !?
Regards, Sebastian Haase PS: hope to see some of you in Leipzig this year [SciPy-user] prime factorization... > Hi all, > Is there any function in scipy that gives the prime factorization? > ie 50 -> [5, 5, 2]? > TIA > Cheers, > > -- > > Fred > > Let me tell you there is another solution: NZMATH > http://tnt.math.metro-u.ac.jp/nzmath/index.html > which is written in Python. > >>> import nzmath.factor.methods as methods > >>> dir(methods) > ['DefaultMethod', 'EllipticCurveMethod', 'MPQSMethod', 'PMinusOneMethod', > 'RhoMethod', 'TrialDivision', '__builtins__', '__doc__', '__file__', > '__name__', 'arith1', 'bigrange', 'ecm', 'ecmfind', 'factor', 'find', 'mpqs', > 'mpqsfind', 'pmom', 'prime', 'rhomethod', 'trialDivision', 'util'] > >>> methods.factor(50) > [(2, 1), (5, 2)] > >>> methods.factor(18440000000000000000) > [(2, 18), (5, 16), (461L, 1)] > Regards, --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "sympy" group.
