Thanks for that. Yes it makes more sense now. MATLAB works when run
using sage-native-execute but not when using !matlab.
Essentially the cause of the problem is that DYLD_LIBRARY_PATH
includes /Applications/sage/local/lib when running MATLAB. Some
library in this folder is obviously replacing the one MATLAB expects
and causing issues - maybe it's libgcc? I'm not sure
export DYLD_LIBRARY_PATH=/Applications/sage/local/lib && matlab
consistently causes the crash from the command line.
What is the best way to fix this (and submit a patch). Is it just that
once a version of Sage is compiled for 10.6 the libraries will no
longer conflict and the problem will go away? Or should I change
matlab.py to call sage-native-execute before matlab? Or should I
change expect.py or pexect.py to always shed the DYLD_LIBRARY_PATH
environment variables? Or something else?
Thanks,
Jonny

This works fine for me in both 32 and 64-bit OS X 10.6. I.e., it definitely doesn't crash for me. Does the student have fink or Darwin Ports installed? Is there a /sw directory?

[sage-support] sage crash on osx 10.6
Hi, A student encountered an error when running sage from the command line on OSX 10.6. When she tries the command sage: point((3,3)) sage crashes and OS X gives the message, /Applications/sage/local/bin/sage-sage: line 199: 5436 Abort trap sage-ipython "$@" -i sage does not crash when creating a point, only when trying to show it, and only from the command line. In Linux, this works fine, and I realize this is OSX so maybe it shouldn't work at all. She didn't try it before upgrading to 10.5, so we were wondering if (1) this is expected behavior; (2) if not, (2a) does anyone else encounter this problem on OSX, or is her computer bonkers?

And I try to avoid using lambda notation whenever possible, because I don't fully understand it even when I do use it, and my students certainly don't. Hence this post. Again, my point was that I inputted a real-valued function to plot3d, and a complex-valued one to complex_plot, and both died. But I don't know how to fix it, unless the code for fast_callable is easier to work with than I think.

[sage-support] Re: plotting and float
By the way, you can make your original example work by using a lambda instead of a symbolic expression: sage: plot3d(lambda x, y: abs(e^(pi*i*x)+e^(pi*i*y)), (0,1), (0,1)) Should work. (Although I'm getting the error "plot variables should be distinct", which I think is a bug; workaround is to change one of the lower bounds to 0.1 instead of 0.) --~--~-~--~~~---~--~~ 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] Firstly, Sage-math 4.1.1 does not work properly and notebook either.
Hi, My computer is Intel Core 2 Quad CPU Q9550 2.83 GHz and OS is Microsoft Windows Xp Professional version 2002 service pack 3. I downloaded VMware player 2.5.3 through sage-math pages. I also downloaded sage-vmware-4.1.1 from sage-math pages. Now when I goto sage through fast link sage_vmx , and write notebook there is this error " Open Firefox to the address http://192.168.23.128 It may take up to about 10 seconds for the server to start.

[sage-support] Re: Maxima Solve sys
JSmath is basically a bunch of javacript routines that takes latex
created from sage and displays in the html file. The html is
generated in my Python script(server,html). When I call JSmath the
first routine is loaded. In the first script it calls another and
this is where the problem occurs. One of the problems is that I am
calling the JSmath from a server. It is a path problem. I can insert
images in the html file.

[sage-support] Re: sage 4.1.1 + sage-mode 0.6 = broken sage-view
hi nick, I've installed CarbonEmacs, the same thing happens.

[sage-support] Sage 4.1.1 illegal instruction on ubuntu 9.04 on Pentium M processor 1.73GHz stepping 08 (Dell inspiron 6000)
Hi, I've been trying without results to run sage 4.1.1 on my Dell inspiron 6000 laptop running Ubuntu 9.04. I tried both the pre-compiled file tar download files for Ubuntu as well as for Debian lenny; both return with frede...@insp6000:~/sage-4.1.1$ ./sage -- | Sage Version 4.1.1, Release Date: 2009-08-14 | | Type notebook() for the GUI, and license() for information.| -- The Sage install tree may have moved. Regenerating Python.pyo and .pyc files that hardcode the install PATH (please wait at most a few minutes)...

[sage-support] Can I define the derivative of un unkown function
I am trying to do the following thing but I am not sure whether this
is possible in sage (though I think it is in Mathematica)
Let's say I define a symbolic function
sage: f=function('f',x)
I would like to issue some command to "tell" sage what the derivative
of f is (for instance : g) so that the command
sage: diff(f)
would yield g
The purpose of this is to use this unknown function in a more complex
derivation scheme.
Any idea out there ?
Thanks for reading
