Hi there
I am trying to teach some simple principles of single compartment models
with sage and I plotted a couple of exponential equations in my
notebook.
Although I got a nice x-axis () and other labels and similar things, I
cannot find a way to plot the y-axis in the vertical axis. Is there
anyway to do it?
You can take a look to my notebook to see what I mean
http://sagenb.org/home/pub/457
Another additional problem is that the LaTeX fonts are pretty small, and
I cannot represent Greek letters (like alpha, tau, pi,etc..) in the
labels (see the syntax bellow).
xlabel = text('Time (Units of $\tau$)',(3,-.10), rgbcolor='black')
This \tau does not show up in the graphic, but strange enough, this
works out of the box (pretty small though)
lnlabel = text('Unrecoverable fraction ($f_{U} = 1 -
f_{S}$)',(4,FS+.05),rgbcolor='black')
thank you very much in advance for your help and care!
Just one remar. There is a fontsize option to text:
xlabel = text('Time (Units of $\tau$)',(3,-.10), rgbcolor='black',
fontsize=30)
William
The second remark is that backslash is an escape character for strings in
(almost) all programming languages. You have to do \\ to get a single
backslash, so this works:
xlabel = text('Time (Units of $\\tau$)',(3,-.10), rgbcolor='black',
fontsize=30)
Or you can do:
xlabel = text(r'Time (Units of $\tau$)',(3,-.10), rgbcolor='black',
fontsize=30)
Thank you very much for your remarks, everything worked fine, except for
that I did not manage to create a vertical oriented y-axis label.
That might not be implemented yet in Sage directly.
I
think the solution would be to import the matplotlib python module and
use it under Sage, however I did not find a proper manual to follow.
Here is how to use matplotlib directly in the Sage notebook:
import pylab as p
p.figure()
t = p.arange(0.01, 2.0, 0.01)
s = p.sin(2 * p.pi * t)
s = p.array([float(f(x)) for x in t])
P = p.plot(t, s, linewidth=4)
p.xlabel('time (s)'); p.ylabel('voltage (mV)')
p.title('Matlab-style plotting in Sage')
p.grid(True)
p.savefig('sage.png')
The above example depends on a function f being defined, e.g.,
x = var('x')
f(x) = sin(3*x)*x+log(x) + 1/(x+1)^2
Thank you very much for your nice example. Actually I became confused
with all the backend stuff, but this example I realize how to use
matplotlib under Sage, although I have to admit I love the plotting
capabilities of Sage. Is there any way I can have a look to the code so
that I might try to implement some new characteristisc (like y-axis,
fontsize of the axis, etc...)
Yes. In fact, the ability to look at the code is one of the main
reasons for Sage's existence! The code for plotting is in the directory:
$SAGE_ROOT/devel/sage/sage/plot/
where $SAGE_ROOT is the directory that contains the sage binary.
Thanks,
Jason

[sage-support] Re: Exterior algebra
Thanks for the help, Everyone. Learning to construct the exact ring I wanted in Singular took some effort, but SuperCommutative() gave me the construction I needed and saved me piles of computation. (I don't know how to apply patches and so didn't attempt the 'native' solution, but I'm grateful for those comments anyway.) (Also, hi again, Martin.)

One could do this with FreeAlgebraQuotient, but I want to compute the exterior algebra over QQ^7, which is large enough (dimension 128) that using that class would be tedious. I had a similar setting: Graded commutative rings, i.e., homogeneous elements in odd degree anticommute among each other, and homogeneous elements in even degree are in the center. An exterior algebra is just a special case (all generators in degree one). My solution was to use Singular's SuperCommutative (http://www.singular.uni-kl.de/Manual/3-0-4/sing_520.htm) in the background. Here, one defines a polynomial ring, and SuperCommutative(m,n) then yields a non-commutative ring in which variables m to n anticommute and have square zero. Unfortunately, SuperCommutative isn't available in libsingular (yet, hint hint...). So, you would need to use Singular directly via the interface, using SuperCommutative(1,n) for implementing exteriour algebra with n generators. SuperCommutative is quite efficiently implemented: Basic arithmetic seems to be nearly as fast as in usual commutative polynomial rings, and you have fast Gröbner basis computations. And the number of generators shouldn't be a problem.

Thanks, Jason Dear Jason, thank you very much for the information!!!. I've just took a look to the source code, and actually, much of what I wanted to do with the sage plot is described in the Graphics class. There are still some things which could be done (fonttype, log-scale, vertical ylabel, etc...) and I heard somebody is working on that for the version 4.0. In any case, I will try first to become more familiar with that and try to implement some of my plot necessities after seen what is new for the new version. Thank you very much for everything!!!

Kevin Horton Hi, What worked for me was to download a jsMath font from http://www.math.union.edu/~dpvc/jsMath/download/jsMath-fonts.html and install the fonts into my ~/.fonts directory. I find that this is often the easiest way to install fonts and of course does not need root permission. Thanks for the suggestion, but I also want to be able to point other PC users at my published sage worksheets. I don't want to force them to manually install fonts. I have discovered that Firefox works fine - it is only IE7 that has the problem. I suspect most of the people who I wish to show my worksheets to already have Firefox installed, so I will not invest any more time on this issue. -- Kevin Horton Ottawa, Canada --~--~-~--~~~---~--~~ 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 URLs: http://www.sagemath.org -~--~~~~--~~--~--~---

For that reason I decided to create howto guides in a sage worksheet format to introduce the colleagues of my group into Sage, so that we can move from mathematica to Sage/Phyton. I tried a couple of examples, that you can visit here: How to plot with Sage: http://sagenb.org/home/pub/399 How to solve limits with Sage: http://sagenb.org/home/pub/398 I found that the sage days 13 (http://wiki.sagemath.org/days13/projects/sagenewbie) were actually doing something very similar applied to different topics that I want to cover too. I was wondering if any of you know about it. I would not mind to collaborate with that and share my worksheets to help other people to become more familiar with Sage. +1 I am also creating similar worksheets, which I'm posting here: http://wiki.wstein.org/09/480b/schedule William I've just realized that everybody can create an account and edit in this wiki. I added a couple of worksheets to the site, i hope somebody find it useful. added to my favorites... :D nice worksheets, and by the way, nice videos explaining the basis of Sage, (this is what a very beginner needs) I will show them in my course. --~--~-~--~~~---~--~~ 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 URLs: http://www.sagemath.org -~--~~~~--~~--~--~---
[sage-support] How to stop wiki?
I've searched sage-support, all the docs, the MoinMoin docs and done a bunch of Googling, but I have not learned how to stop the wiki. A ctrl-C kills it, but it immediately starts up again, but with the port number incremented by one. Same thing if I use kill to stop the wiki's twisted server PID. Any hints would be appreciated. -- Kevin Horton Ottawa, Canada --~--~-~--~~~---~--~~ 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 URLs: http://www.sagemath.org -~--~~~~--~~--~--~---

That works. Thank you very much.

Davide (the author) at least occasionally reads this list. He might ask for more details, or he might already know what is going on. I am curious, though: when you click on the jsmath icon in the lower right, a panel pops up and says what types of fonts jsmath is using. Is it using the image fonts?

[sage-support] Re: setup a sage server
ggrafendorfer wrote: Hi all, thank you very much for your answers, especially Dan for the link and the subtle distinction between sage- server and notebook-server (allthough with server-version I ment the sage copy on our department server oposed to that on my local computer), but anyway, it helped me do understand things much better now, unfortunately my time is restricted and I know 'vmware' just by it's name and that it's a virtual machine, so my plan now is just to start with a python (sage) webinterface (which I have learned last night how to do that :-)) where the user can insert some numbers, and then delegate the task to sage, as this is actually what I (actually my supervisor) wanted with the smallest possible effort (I mean time, not resources on our server) acually sage is a total overkill for this task, but I don't want to rewrite my program, Again, we caution you that access to Sage is equivalent to full access on the computer as the user that Sage is running as. People running Sage commands can delete files, send files over the internet, send email, download and run arbitrary programs, etc. If you are letting arbitrary people give you Sage commands, you are basically letting them sit down at your computer and they can do whatever you can do. That's why we strongly encourage people to run the vmware image of Sage when doing a public server. It's as simple as installing vmware (a couple of clicks, basically), then downloading and double-clicking on the sage vmware image. You might also have to change one setting in the vmware image; I'm not sure. Someone running sage commands can still mess up things inside of the virtual machine, but it's trivial to press a button to erase any changes to the image and start fresh. If Sage is an overkill, maybe sympy might be more sufficient? The same security issues above apply, though.

[sage-support] I was using sage-3.1.4 upgrade to 3.4 and have memory issues
I hope you can help me to recover my sage-usability, I was working with a sage-vmware-3.1.4 installation on a windows XP host with 512MB RAM without any problem, I recently upgrade to the last build version 3.4, but as far as I gave the notebook login, it killed the notebook and restart automatically again the login option connections, so I played a little with the configuration of the VMware troubleshooting arrangement of memory trying to fix this problem, but still without accomplishing to put it to work at all. So I went back, to install the previous version available in the download page: sage-vmware-3.2.3, it worked for a while but very slowly all the time, after that when I tried to run sage_vmx.vmx, the VMware console sent a complaining message like not enough memory for running the given virtual machine and suggest that restarting the host if the VM was working previously will fix the problem, I tried that many times, but still sage cannot restart as told. Now I am wondering that I was in better conditions before the upgrade trial, because at least I could use sage in my research and now I don't have anything to work with, given that I have deleted my previous directory and as far as I know the old build version is not available to download. Then, it would be helpful to other people, if you can put some warnings about the new installation requirements for sage to go. Of course I know that I could reinstall the old one from source (I am a Xcygwin not an Ubuntu fan, so it will take me a lot more of my patience), but meanwhile I shall need to rest a little to try this other option, while my today's nightmare dissipates. So, I would appreciate very much any suggestion about what to do, to get sage working again in the least painless way.

The entire problem is that the default memsize on the virtual machine was increased in 3.2.3 to 512 from 300-ish in 3.1.4. Sage worked for you before, not because you used 3.1.4, but because of a single default setting in the virtual machine. Given that your computer only has 512MB RAM, it's no surprise that a virtual machine can't work if it tries to allocate 512MB RAM too.
