I don't if you call coding theory "other than math" but there are
developers who are not in math departments (eg, CJ, a GUAVA
developer is in the "Computing, Communications & Electronics" dept).

I don't use windows but the way you are trying is definitely wrong.
In linux you just type "sage -i gap_packages-4.4.10_4" and it downloads
it (assuming you have internet) and installs it for you. It also loads the GAP
packages into the saved GAP workspace. Therefore, once it is installed,
all of
It might work if you try coercing f = B[0] first into
R2. = PolynomialRing(CC, 2, 'xy')
then applying factor or whatever to R2(f). I haven't tried it with your
problem but that general idea has worked for me in similar situations.

One way is, for example,
sage: J = range(3)
sage: A = [ZZ(i^2)+1 for i in J]
sage: s = IndexedSequence(A,J)
sage: s.plot_histogram()
using http://www.sagemath.org/hg/sage-main/file/211b127eab5d/sage/gsl/dft.py

I can verify this on an intel mac *and* that
sage: contour_plot(y-1,(-10,10),(-10,10),fill=False,contours=2,plot_points=100)
sage: contour_plot(y-1,(-10,10),(-10,10),fill=False,contours=1,plot_points=100)

I believe Sage simply calls Maxima for the solution. Since you
obviously know the
most about the problem, perhaps the easiest thing to do would be to determine
that it is Sage and not Maxima that is at fault. Perhaps you could see if
the solution is obtained in Maxima? (On the command line of Sage

I don't know how to fix it so that parametric_plot works. However, the
following workaround at least gives you a plot:
sage: a = RR(1729^(1/3))
sage: f1 = lambda x: RR(real((1729 - x^3)^(1/3)))
sage: f2 = lambda x: RR(real(-(-1729 + x^3)^(1/3)))
sage: L1 = [(x,f1(x)) for x in srange(-a+0.1,-15,0.

At the moment,
(a) "piecewise" is only set up for piecewise polynomials,
(b) the "integrate" command is "integral".
So, for your function (which is piecewise polynomial), this should
work:
sage: f1a = lambda x: -x+1; f1b = lambda x: x+1
sage: f2a = lambda x : -(x - 2) - 1; f2b = lambda x : (x - 2
Done:

Hi:
It seems like I saw this reported already but can't find it now.
I'm thinking I'm doing something stupid, but can't figure it out
and was wondering if someone on this list can see the problem.
My usual procedure for creating a patch is as follows:
1. Take a file I want to edit, say linear_co
,k,q):
> r"""
> Return the gaussian binomial

>\binom{n}{k}_q = \frac{(1-q^n)(1-q^{n-1})\cdots (1-q^{n-k+1})}
> {(1-q)(1-q^2)\cdots (1-q^k)}.
> $$
>

Maybe printing the values makes it clearer?
sage: R = Integers(125)
sage: g = R.multiplicative_generator(); g
2
sage: b = g^3; b
8
sage: a = b^17; a
123
sage: a.log(b)
17
So, 123 = 8^(17) mod 125:
sage: R(123).log(8)
17
sage: R(123) == R(8)^(17)
True

I'm not sure what the cause of the error is but, FYI, some Riemann sum stuff is
already implemented in piecewise.py.

Hi:
Suppose a finite matrix group G generated by 3x3 matrices
A1, A2, ..., Ar acts on the polynomial ring QQ[x,y,z].
Singular has a command which computes a basis of
invariants. I'm stuck trying to run them in SAGE. The commands at

No, but

Reported to trac and fixed (I think).

Thank you for your report.
Note
sage: x = "(1,2)(3,7)(4,6)(5,8)"
sage: PermutationGroup([x])
Permutation Group with generators [(1,2)(3,7)(4,6)(5,8)]
works fine. The result of gap.Image is an instance of the
GapElement class, so it looks like it is a syntax issue for
such elements. I can take a

By coincidence, I recently installed sage from source on a fresh
ubuntu install and the instructions on
http://www.sagemath.org/doc/html/inst/node5.html
worked for me. In other words, if you type
sudo apt-get install gcc-4.2-base # or the latest version available

Hi:
Either a bug in combinat.py's permutations, or an indication that
it needs to be rewritten. (permutations is a GAP wrapper which
I might have written, so should probably fix ...)
