Hi,
I would like to know if there is plans to allow direct editing of the
html on a notebook without having to go to the "Edit" tab and entering
html there.
I was thinking it would be nice to have a simple javascript html
editor that would come up when one clicks on text outside eveluation
boxes
There has been some work on this recently, by Jason Grout, on adding
the tinyMCE editor to the notebook. The idea is that a shift-click
will create a html block that can be edited by tinyMCE.
Unfortunately at the moment that feature addition is somewhat
intertangled with a refactoring of various
Dear Simon,
Thanks for your answer.
What I want is for a linear combination X(t):=p(t)*y1(t) + q(t)*y2(t)
(p and q are known functions) to construct a new
second-order differential equation for X(t) from the orgininal
system. For a second-order system this can easily be done by hand.
I have, ho

It's been awhile since I used Maple and I still don't understand your question.
Is it possible to copy+paste a Maple session in and then just ask
"can this be done in sage"?

Unfortunately, at the moment it has to be a permutation group. Here is one way:
sage: F = GF(5)
sage: S = SL(2,5); S.gens()
[
[2 0]
[0 3],
[4 1]
[4 0]
]
sage: gens = [matrix(F,2,[2,0, 0, 3]), matrix(F,2, [4,1, 4,0])]
sage: G = MatrixGroup(gens); G
Matrix group over Finite Field of size 5 with 2

That's good idea, William. Let me back up to and change my question

Hi,
I'm an engineer by training, so my knowledge of
mathematics is very applied. A lot of things in
Sage deal with Groups, Rings, and Fields so I'd
like to broaden and improve my mathematics knowledge.
Could someone suggest a good introductory reference
(and possibly an intermediate one) so I can
thank you so much for your help .

I am puzzled by one of the binaries: http://sage.math.washington.edu/
sage/osx/powerpc/sage-3.2-G5-PowerMacintosh-Darwin.dmg
Does the "G5" in the name mean it's specific for the G5 processor?
Usually the binaries are named according to the OSX version -- is
this one for OSX 10.4 or 10.5?

Hi folks,
Perhaps someone can give a better answer to the question below? I
haven't explored enough with random matrices and finite fields in Sage
to competently answer the question.

MS = MatrixSpace(GF(5), 4, 4)
M = MS.random_element()
You can just use the random_matrix command:
sage: random_matrix(GF(5), 4, 4)
[3 0 4 3]
[4 1 1 4]
[2 3 3 4]
[4 4 1 0]

Just search for "jsMath failed to set up" in the sage-support forum
and you find out what to do (need to install the tex fonts from
jsMath). Many people had this problem and I believe that the solution
is being incorporated into the documentation.
Good luck!
