Quoting William Stein wst...@gmail.com:
This is something else -- this is a problem where somehow some users
worksheets got blanked out, probably due to a server crash (?). It
was on the new server.
And unfortunately, I had temporarily removed snapshots, since they
were causing trouble
I am very low on time for Sage development right now, but I am
interested in having matrix ordering supported in Sage. I will put
this on my Sage to-do list and help out when I can (unfortunately my
Sage to-do list is getting pretty long).
I agree with John that Simon's example:

I tried using the function list_plot3d to visualize a 2d matrix, but
it doesn't seem to work. I tried it with both a numpy array and a sage
matrix and in both cases the Jmol applet loads but then all I see is a

Hello,
When I try to execute
var('x y z')
implicit_plot3d(x^2+y^2+z^2==4, (x, -3, 3), (y, -3,3), (z, -3,3))
within http://www.sagenb.org using Firefox the Jmol applet apparently
loads but then gives the message 'Jmol script terminated' (lower left
corner of browser). Here is the error from the

Yeah, the sample code works for me too. I'm not sure I see what's
different about what I'm doing.
Here's an example of something that doesn't work for me:
var(rho_X rho_Y R)
R=6
rho=sqrt(rho_X^2+rho_Y^2)
EE(rho_X,rho_Y)=exp(-rho/R)
ee=fast_float(EE)
grid=np.arange(-32,32,0.05)
eeM=[[ee(x,y) for
Is there anyway to display an expression in the notebook, but not have
it calculate? Such sqrt(4)+sqrt(12). Don't simplify. Or integral
(x^2,x)
Thanx

Sage is unable to simplify the following expression to zero:
log( (a-1)/a ) - log(a-1) + log(a)
I have tried assuming a1 but that does not work.
Help will be appreciated.
Tanks!

(log( (a-1)/a ) - log(a-1) + log(a)).full_simplify()
works for me.

I'm not sure what false-friend means here. Appreciated is an
German has this expression too for the concept. I think that false
cognate is the usual English term.
