This works:
graphs.CubeGraph(4).shortest_paths('')
but this don't:
graphs.CubeGraph(4).shortest_path_all_pairs()
Maybe the shortest_path_all_pairs function needs a
by_weight=False parameter too (like the other shortest paths
functions).
I also would like to have a function

Hello,
After uploading a worksheet from my PC to the sagenb.org server, I
can't edit or evaluate cells within it. I'm receiving the error

I am interested in the use of Sage as a teaching tool at all grade
levels. At the moment, I'm trying to weave Sage into an introductory
algebra curriculum.
I can graph all the basic functions with plot(x), replacing x with
x^2, x^3, 1/x, etc. The one I can't get to work is x^(1/3). I've
tried

Hi Andy,
I had the exact same question a few days ago. There are
many issues involved here, but the short answer to your
question (provided by Carl Witty) is:
you can plot x^(1/3) with
show(plot(lambda x : RR(x).nth_root(3), -10, 10),

Looking at the repository, it seems as if I wrote these functions, but
I don't think that's right. Maybe this was one of the patches I merged
from Jason Grout, while his name wasn't getting on the changesets. I
seem to remember Emily Kirkman working on path functions, also. I'm
not sure what the

By the way, is the following a bug?
sage: singular.LIB('ncall.lib')
sage: R=singular.ring(0,'(x1,x12,x2)','dp')
sage: C=singular.matrix(3,3,'1,-1,-1, -1,1,-1, -1,-1,1')
I also would like to have a function all_shortest_paths(u,v), which
returns all shortest paths from u to v.

Thanks for your help. I had searched the group and found the thread
about nth roots, but I wasn't putting it together with the plot
statement correctly.
Thanks also to Jason for publishing an illustration -- good idea. The
published worksheets are a great resource for learning Sage and

I have a local install of Matlab 2007b and a local install of Sage.
When I run a Matlab command from Sage, e.g. the command
matlab.eval('2+2')
I get the error Unable to start matlab because the command 'matlab -
nodisplay' failed. The location of the Matlab executable is
