[sage-support] BoxPlot in Sage: how do we plot?
I don't see a direct command in sage for BoxPlot. Thus, I've tried many 'R' versions of boxplot (like: r.bxplot, r.bplot, r.boxplot) on a dataset I have, but could not get a plot... I am using the latest Sage Notebook (v 4.3.3) Would you pls help? -- To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to sage-support+unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-support URL: http://www.sagemath.org

[sage-support] problem doctesting files outside Sage library
Hello,
I'm having trouble doctesting a file outside the Sage library:
$ sage -t example-sageexample.sage
sage -t "example-sageexample.sage"
A mysterious error (perhaps a memory error?) occurred, which may have
crashed doctest.
[0.2 s]
--
The following tests failed:
sage -t "example-sageexample.sage" # Segfault
Total time for all tests: 0.2 seconds
This happens with 4.3.3 on both Linux and OS X. According to the
developer guide, this should work, but it fails, both with the .sage and
.py files. Any ideas? I'm attaching the offending file, which is related
to a new SageTeX feature that Nicolas Thiery developed.

Re: [sage-support] Entering matrices whose elements are functions of row/column indices?
Here is another way:
sage: coeffs = [[i^2-j for j in range(6)] for i in range(6)]
sage: matrix(coeffs)
[ 0 -1 -2 -3 -4 -5]
[ 1 0 -1 -2 -3 -4]

[sage-support] Entering matrices whose elements are functions of row/column indices?
This can be done in maxima:
genmatrix(lambda([i,j],i-j),6,6);
for example. But is there an easy Sage way of doing this? If I enter
sage: M=maxima('genmatrix(lambda([i,j],i-j),6,6)')
then I obtain a Maxima matrix, which then has to turned into a Sage
matrix (I don't know how to do this either). Clearly I could:
sage: M=matrix(ZZ,6,6)
sage: for i in range(6):
: for j in range(6):
: M[i,j]=i-j
but that seems a bit longwinded. Is there an easy straightforward
way?
Thanks,
Alasdair

[sage-support] Simplify matrix with variables
Hello there,
I have a little kinematic project running.
I have a matrix with Denavit-Hartenberg parameters for each joint. See
http://upload.wikimedia.org/math/6/e/3/6e3a9d7ad118c01e0e8b06cdc6d0205f.png
In my case everything except theta is constant. I need to multiply
this matrix with itself for each joint. To save some computing time I
want to simplify the matrix.
My matrix looks like this:
dh = matrix([[cos(theta), sin(theta) * cos(x), sin(theta) * sin(x), r
* cos(theta)],
[sin(theta), cos(theta) * cos(x), -cos(theta) *
sin(x), r * sin(theta)],
[0, sin(x), cos(x), d],
[0, 0, 0, 1]])
Where x is the variable for alpha.
When I want to print the matrix for the second and following matrixes,
maxima always crashes. Therefore I can't multiply and simplify the
matrixes.
Any suggestions?! Attached the traceback.

I'd want to make a beamer-presentation with these plots and want to help my students see the 3d. Can Sage make stereographic 3-d plots? If there's a way to get a PNG image of such a plot out of Sage, then you can get it into your presentation. What exactly do you mean by "stereographic"? Do you mean the kinds of image in which there's two images, from slightly different angles, and you project it using polarizing filters and the students wear polarized glasses? Or those "magic eye" images that look like static unless you cross your eyes just right? Sage (via Jmol) can do both. Right click on the applet for a menu. You can then save the image via the "get image" (or something like that) button. My guess, though, is that if you are already using a computer and a projector, it would be better to use an actual Jmol applet in your class. Then, instead of a three-dimensional static image, your students see something interactive, that can be twisted around, zoomed in and out, and so on. That works too. Of course you can zoom and twist a stereographic image, getting the best of both. - Robert -- To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to sage-support+unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-support URL: http://www.sagemath.org
