Subject: Sage ModularForms() error?

David Joyner,
When using the sagecell.sagemath.org server,
when I evaluate the command:
Modula
plemented in Sage for dimensions of weight 1 modular form spaces.

I think that "by improve this", M. is asking if there is a plan to implement

Thank you, so what to do for Python function? Matlab had general purpose

Thank you, that's helpful. Is there a way to get all roots of a Python
function on an interval?

Thank you, that makes sense. My Python function is not continuous though,
has poles, so I'll probably have to plot it to find its zeros...

Have zeros of order 2 too, so the sign change doesn't help in general, but
may work for some zeros. Thank you!...

I know this is some work, but can you create a partition with a 64 bit debian?
AFAIK, the need for 32 bit, for most people, expired some time ago.

I don't know the problem. An obvious thought: I guess you know
you have amd64 bit ubuntu installed as opposed to 32 bit?
This wasn't clear from your email.
Also, one website suggested that notebook has an
(intel) centrino chip, not the amd64 bit chip the binary I think
is built for. I could easil
er.
Also, what is the proper way to do this? I'm guessing one should
write wrapper classes as in the interfaces directory but is swig better?

Would it be better to add a method="recursive" option to the current
subs method?
To answer your question though, I think the procedure to add anything
to Sage is to create a patch and submit it to trac. See the
Programming guide for
some hints.

This probably doesn't help, but there is a method in axes.py called
"tasteless_tick_marks" which I guess you have to figure out how to use
somehow.
sage: from sage.plot.axes import Axes

I don't have the answer but just to clarify.
Since at least for me (in the US) google chrome is not available
on any linux or mac platform, I'm guessing
(a) you have google chrome running
on a windows pc and sage running on a separate machine?
(b) You are trying to run sage via the windows pc's
Yes,
sage: G = PGL(2,3)
sage: G.sylow_subgroup(3)
Permutation Group with generators [(2,4,3)]
Type
sage: G.sylow_subgroup?
for more details.

A couple of sources over the web:

and (a bit harder and for group theory only)
(b) http://www.opensourcemath.org/books/gaglione-gp-thry/

might fit the bill. Next level up from (a) might be

But tcl/tk is not a python package. tkinter is the python interface to
it and it is included with every python distribution (including Sage's).
The problem is that to import it, tkinter.py looks for tcl/tk using some
magic I couldn't figure out.
Adrian's suggestion (or William's, and I think now
I wonder if this should be mentioned in install.tex somewhere?

Looks like the Sage tutorial except it has a lot of exercises and statistical
examples. There are also some cool dynamical systems examples.
I agree, that the tutorial at least needs more statisitcs.
I'm not how sure the new documentation system rest/sphynx handles graphics.
If graphics are no pr

I get
sage: var('x')
x
sage: f = sin(x)/x
sage: g = f.integrate(x)
sage: g
integrate(sin(x)/x, x)
in 3.2.1.rc1. Personally, I would call this a missing feature, not a bug.
Interestingly, it can compute
sage: f.integrate(x,0,infinity)
pi/2
sage: f.integrate(x,-infinity,infinity)
pi

You forgot the "[0]":
sage: m = matrix([[1,2,2],[2,1,2],[2,2,1]]); m

[2 1 2]
[2 2 1]

(1, 1, 1)

Personally I don't see how
As a guess, for a substitution like you want to work, the following
much simpler computation
sage: t = var('t')
sage: x = function('x', t)
sage: y = function('y', x)
sage: diff(y,t)
diff(y(x(t)), t, 1)
should yield not diff(y(x(t)), t, 1) but perhaps something like
d
One way to do it (for a 10x10):
sage: n = 10
sage: M = Matrix(n,n,[[1/(i+j) for i in range(1,11)] for j in range(1,11)])
sage: M
