[sage-support] Re: Bug: running scripts broken
My memory could be wrong, but I feel that this exact problem has
occurred before. (The problem of running scripts on the command line not
working -- not necessarily the exact same underlying cause for the
problem.)
This kind of basic functionality should probably be tested somewhere
automatically. Maybe a doctect with a line like
sage: os.system('.\sage something_or_other.sage')
might work. Or maybe this would need to be somehow tested outside the
doctest framework. I don't know. Just a thought.

I've been guessing that it's somewhat like a Mathematica notebook. If so, great ... I'm looking for a notebook kind of thing to use with scipy (etc.).

[sage-support] SAGE-2.8.3.3 released!
Hi, I have released sage-2.8.3.3. This is mostly a relatively minor bug fix release on the way to 2.8.4. I won't be posting binaries. "sage -upgrade" should be relatively painless fromm 2.8.3. Some of the contributors and contributions are listed below. High level changelog: * Craig Citro -- fixes to build process (involving c_lib) * Craig Citro -- modular forms bugfix (for projection map); added some number fields functionality * Pablo De Napoli (refereed by Martin Albrecht) -- added minpoly for finite field elements. * Robert Bradshaw (and William Stein) -- created a separate java3d spkg * Mike Hansen -- Bug fixes * Michael Abshoff -- bug fixes * William Stein -- bug fixes and lots more doctests. -- William Stein Associate Professor of Mathematics University of Washington http://www.williamstein.org --~--~-~--~~~---~--~~ To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to [EMAIL PROTECTED] For more options, visit this group at http://groups.google.com/group/sage-support URLs: http://sage.math.washington.edu/sage/ and http://sage.scipy.org/sage/ -~--~~~~--~~--~--~---

Hey, good point!
Just change to_V(z) to "V(z)" everywhere. Here's a new worksheet:
ahmad -- sage-support
system:sage
{{{id=0|
k. = GF(2^5)
}}}
{{{id=1|
k
///
Finite Field in a of size 2^5
}}}
{{{id=2|
V = k.vector_space()
}}}
{{{id=3|
z = (1+a)^17; z
///
a^3 + a + 1
}}}
{{{id=6|
B2 = [(a+1)^(2^i) for i in range(k.degree())]
}}}
{{{id=7|
W = [V(b) for b in B2]
}}}
{{{id=8|
V.span(W).dimension()
///
5
}}}
{{{id=9|
W0 = V.span_of_basis(W)
}}}
{{{id=10|
def in_terms_of_normal_basis(z):
return W0.coordinates(z)
}}}
{{{id=11|
in_terms_of_normal_basis(a+1)
///
[1, 0, 0, 0, 0]
}}}
{{{id=12|
in_terms_of_normal_basis(1 + a + a^2 + a^3)
///
[1, 0, 0, 1, 0]
}}}

I think it would be nice to have in_terms_of_normal_basis
(of course you need to change "2" to "p" in general).
However, I don't understand what to_V does that built-in
coersion doesn't already do:
sage: k. = GF(2^5)
sage: V = k.vector_space()
sage: z = (1+a)^17; z
a^3 + a + 1
sage: V(z)
(1, 1, 0, 1, 0)
This seems to be the same output you gave for to_V(z),
or am I missing something?

[sage-support] Re: Changing basis in finite fields
Thank you very much! These were surprisingly fast replies! I tried to
run william's code, but appearently my version of sage does not
understand padded_list property:
z.polynomial().padded_list(5)
sage: z.polynomial().padded_list(5)
---
Traceback (most recent call
last)
/home/amadi/Programmes/Sage/sage-2.6.linux32bit-i686-Linux/ in ()
: 'Polynomial_dense_mod_p' object
has no attribute 'padded_list'
I'm writing it while I'm downloading Sage again.

[sage-support] Re: Notebook servers down?
Oh, are they just subservers of sage.math? I wasn't aware of that - I know that one is often overburdened. Perhaps I should try again tomorrow.

[sage-support] Notebook servers down?
I cannot link to either sagenb.com or .org right now, and if possible I'd like confirmation that they are down. I assume that I just missed a post somewhere along the line about this, presumably having to do with the new notebook server setup, but in case this is in fact a problem on my local network I would appreciate any kind soul confirming this for me. If anyone has info on when they would be back up, I could use that as well. --~--~-~--~~~---~--~~ To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to [EMAIL PROTECTED] For more options, visit this group at http://groups.google.com/group/sage-support URLs: http://sage.math.washington.edu/sage/ and http://sage.scipy.org/sage/ -~--~~~~--~~--~--~---
[sage-support] Bug: big complex numbers
Hi,
it seems there is a bug in the implementation of complex numbers. Defining a
number with imaginary part bigger or equal 1E8 gets an exception error.
Best,
Marek

[sage-support] Re: Bug: big complex numbers
Markus,
Thanks for this bug report, which I've made
http://trac.sagemath.org/sage_trac/ticket/587
This will be great fodder for our bug squash even this Thursday
at 10am!
