And, since NZMATH is a Python library, you can also very easily use it in Sage (http://sagemath.org). sage: install_package('nzmath-1.0.0') sage: import nzmath.prime sage: nzmath.prime.nextPrime(1000) 1009 sage: import nzmath.matrix sage: preparser(False) sage: A = nzmath.matrix.Matrix(2, 2, [1, 2]+[5, 6]); A [1, 2]+[5, 6] sage: import nzmath.ecpp /Users/wstein/sage/build/sage/local/lib/python2.6/site-packages/nzmath/real.py:214: DeprecationWarning: RelativeError is deprecated warnings.warn(DeprecationWarning("RelativeError is deprecated")) python(7449,0x7fff7093bbe0) malloc: *** mmap(size=14148475504058368) failed (error code=12) *** error: can't allocate region *** set a breakpoint in malloc_error_break to debug MemoryError [[Bummer, since ECPP = Elliptic Curve Primality Proving is one thing I know of that NZMATH has that Sage doesn't...]] sage: import nzmath.round2 sage: nzmath.round2.round2([1,2,5,1]) ([[Rational(1, 1), Rational(0, 1), Rational(0, 1)], [Rational(0, 1), Rational(1, 1), Rational(0, 1)], [Rational(2, 3), Rational(0, 1), Rational(1, 3)]], Rational(-31, 1)) sage: import nzmath.factor sage: x = int(next_prime(10**5)*next_prime(10**12)); x 100003000003900117 sage: nzmath.factor.ecm.ecm(x) 100003L sage: nzmath.factor.find.trialDivision(x) 100003 sage: nzmath.factor.mpqs.mpqs(x) [(100003L, 1), (1000000000039L, 1)] sage: import nzmath.permute sage: nzmath.permute.PermGroup(['a','b','c','d','e']) ['a', 'b', 'c', 'd', 'e'] -- William -- William Stein Professor of Mathematics University of Washington http://wstein.org -- To post to this group, send an email to sage-devel@googlegroups.com To unsubscribe from this group, send an email to sage-devel+unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-devel URL: http://www.sagemath.org
