Hi there -
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 inc

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
wo
It's fixed! I uploaded another worksheet, and it worked as expected.
Thank you for the quick response, and kudos for the impressive work of
bringing Sage into reality.

Dear John,

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 o

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), figsize=[5,5
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
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

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 "all_shorte
