sympy 0.6.4.beta3 released
Ondrej Certik
sympy 0.6.4 beta3 is out. Tarballs available here:
http://code.google.com/p/sympy/downloads/list
or from our front page.
This is the last beta and unless there show up some release critical
bugs, I expect to release the final 0.6.4 on Tuesday or Wednesday.
Changes since the last beta2 attached. Besides lots of bugfixes, sympy
now has a robust multivariate factorization. In some cases it's even
faster than Maxima via Sage:
sympy:
In [1]: time factor(2*x*y*z + x*y**2 + x*z**2 + y*x**2 + y*z**2 +
z*x**2 + z*y**2)
CPU times: user 0.04 s, sys: 0.00 s, total: 0.04 s
Wall time: 0.04 s
Out[2]: (x + y)⋅(y + z)⋅(x + z)
Sage:
sage: var("x y z")
(x, y, z)
sage: time factor(y*z^2 + x*z^2 + y^2*z + 2*x*y*z + x^2*z + x*y^2 + x^2*y)
CPU times: user 0.09 s, sys: 0.03 s, total: 0.12 s
Wall time: 2.12 s
(y + x)*(z + x)*(z + y)
sage: time factor(y*z^2 + x*z^2 + y^2*z + 2*x*y*z + x^2*z + x*y^2 + x^2*y)
CPU times: user 0.03 s, sys: 0.01 s, total: 0.04 s
Wall time: 0.21 s
(y + x)*(z + x)*(z + y)
sage: time factor(y*z^2 + x*z^2 + y^2*z + 2*x*y*z + x^2*z + x*y^2 + x^2*y)
CPU times: user 0.02 s, sys: 0.01 s, total: 0.04 s
Wall time: 0.19 s
(y + x)*(z + x)*(z + y)
sage: time factor(y*z^2 + x*z^2 + y^2*z + 2*x*y*z + x^2*z + x*y^2 + x^2*y)
CPU times: user 0.04 s, sys: 0.00 s, total: 0.05 s
Wall time: 0.21 s
(y + x)*(z + x)*(z + y)
That was implemented by Mateusz Paprocki. Great job again Mateusz!
In some other cases it takes about the same, in some more complex
cases it takes longer than maxima, but it always returns, and I think
it's a great start. There are still possible rooms for improvements,
as Mateusz says here:
