I had the same problem. Just disregard those instructions.
If the terminal with a sage prompt opens, you are o.k.

How are you starting up Sage? If you're starting up sage via
/path/into/folder/sage
then you'll have to do
/path/into/folder/sage -b

Thanks for the help. I made the changes
but failed to recompile. Here is what I did:
(test is my home name) where is this sage binary?
Laptop-3:~ test$ sage -b
-bash: sage: command not found
Laptop-3:/ test$ sage -b
-bash: sage: command not found
Laptop-3:sage test$ sage -b
-bash: sage: command
Does anyone know what's up with this weird error? Sage can multiply a
symbolic variable and a constant of a polynomial ring R but not a
symbolic variable and an element of R.base_ring().

We don't have the Maxima function trigreduce wrapped in Sage, but you
can access it like this:
sage: f = cos(q1)*cos(q2) - sin

Thanks for your reply;
As I am completely new to sage I do not know how to
perform the indicated change. I looked at the file
sage/devel/sage/sage/matrix0.pyx
but could not figure out how and where to add
the function sage.matrix.matrix0.set_latex_delimiters('[',']')

For a "normal" matrix (i.e., not symbolic), you'll probably want to use
the .eige

I'd definitely go with option (1), as long as you don't mind leaving
it building for a few hours. Jaap was already nice enough to post
Hello everyone!
I am running Sage Version 3.2.3, Release Date: 2009-01-05 in a virtual
machine under Windows Vista.
I am trying to compute the variety of an ideal in a Boolean Polynomial
Ring. From what I have seen in previous posts, that doesn't seem to
work directly. So instead I use the Boole
In integrals variable integration limits work fine with sage.
Now I would like to plot the variable integration range with plot3d or
parametric_plot3d using variable plot range limits:
u,v = var('u v')
parametric_plot3d([u, v, u*0.1], (u, 0, 6), (v, 0, u))
But I get the following errors message:
This seems to work:
given a symbolic matrix P of dimension 2x2 do:
EVECP = maxima(P).eigenvectors()
EVEC1 = EVECP.part(2)
(first eigenvector)
EVEC2 = EVECP.part(3)
(second eigenvector)
EIGENVECT = (matrix(SR, 2,2, [EVEC1.sage(), EVEC2.sage()])).transpose
()
Thanks again for your help.
The textbook I am teaching linear algebra from prints matrices
with brackets as delimeters. [ ]. Hence when I set a test and
write solutions with LateX I wish to use the same notation for
matrices as used in the text.

Compiling from source is straightforward, but takes so

Hi Craig,
I think it is better option (1), but where can I get 3.4.rcl? I don't
see it in the website of Sage.
In your opinion, which option is better?

How can I collect the eigenvectors to form an eigenvector matrix ?
I have tried all matrix commands and I always get some error !
Sorry,

i have trouble in collecting the eigenvectors to form an eigenvector
matrix (in the order given by the eigenvalue computation...).
How can i do this ?
I have tried all matrix commands.

Hello all
Maxima is much better when drawing 2D plots of functions with jump
discontinuity.
Sage makes a vertical lines at disontinuities, compare
A=plot(1/(x^2-1),(x,-3,3))
show(A,ymax=10,ymin=-10)
in sage and
plot2d(1/(x^2-1),[x,-3,3],[y,-10,10])
in Maxima. Is it possible to remove these al

It's probably because no one has written it yet. I think it'd be great
to have. We welcome any patches to do that.
You can do the same thing using the apply_ma

yes, this is what i want !
BUT i cant compute the eigenvectors symbolically within SAGE.
So for example
A.eigenvectors()
gives the error:
AttributeError: 'sage.matrix.matrix_symbolic_dense.Matrix_symbolic_'
object has no attribute 'eigenvectors'
how can i now compute those eigenvectors within
Hi,
I've got a question.
When you have 2 variables q1 and q2, is it possible to simplify an
expression like this:
cos(q1)*cos(q2) - sin(q1)*sin(q2)
to obtain the following result : cos(q1+q2) ?
Thanks in advance
