### Solving linear matrix equations with scipy

```Hi all,

Are there any efforts to add solvers for linear matrix equations to
scipy ?

Is this only true for Panther?  What's the situation (re: libraries)
with Jaguar?

I know that it's a bit unfair to ask the plot routines to plot complex data but I would expect an error, not python to crash. I'm running the latest SciPy release on Windows XP. Example code below crashes. You probably want to plot the modulus of the complex number. It's interesting that if you use plt.plot(b) it gives you an error message that the array is complex then plots the modulus of b for you! Nice error trapping. gplt failes as you say. Cliff

At this point python\pythonw crashes with the following error "python.exe has encountered a problem and needs to close. We are sorry for the inconvenience." If anyone can help me resolve this then I would greatly appreciate it.

### Reboot and Zope Upgrade on SciPy.org

```Hi all,

There will be a short (possibly longer than short, if all doesn't go
well) service outage in a couple of hours on scipy.org (sometime between
6 and 7PM CST).  All scipy.org/scipy.net services will be unavailable
during this time.  This includes mailing lists, the website, CVS, etc.
I will be performing routine maintenence, a kernel upgrade, and a Zope
upgrade.  I expect the outage to last about five to ten minutes, though
Zope has historically thwarted my attempts to achieve a quick and

Nothing should change significantly on the server, as the Zope upgrade
is minor (2.6.1 to 2.6.2).  There are plans afoot to bring SciPy.org
into the modern age with a migration to Plone instead of the older CMF
that we're currently using.  The planners (mainly me) are adragging
their afeet, however, so there's no telling when the switch will be
pulled.  If you have useful content (or merely content you are fond of)
on the site that uses DTML, it would be in all of our interests for you
to consider converting it to using ZPT or structured text.  DTML is
apparently deprecated in Plone, and there also seems to be some other
content type issues that we'll be fighting with one day in the not too
distant future.  Let me know if you have anything there, and I'll see if
I can assist with getting it ready for the migration to Plone.

Holler if this service outage will cause significant pain for anyone.

Thanks!

### SciPy.org is back up

```Hi all,

The upgrades seem to have gone smoothly, and the website, lists, mail,
CVS, etc. should all be available again on scipy.org.  If you run into
any problems, let me know.

Thanks!

### Problem with scipy_distutils

I'm trying build a FORTRAN module using scipy_distutils. Due to some

I remember that this issue has been come up earlier but I don't exactly
recall the solution. What Python, ifc versions are you using?
This "-R" switch comes from runtime_library_dir_option method
of distutils/unixccompiler.py, see the comment in this file,
sending a fix to Python people might be a good idea.

I'm using ifc 7.1 and python 2.3. I found runtime_library_dir_option
and read the message about some buggy code, but the "-Xlinker" option
is specific to ifc so I don't think it should be solved in
distutils/unixccompiler.py, but there where the FORTRAN specific parts
of the code are defined, so the class intel_ia32_fortran_compiler in
scipy_distutils/command/build_flib.py would be the place to go, but it
does not work, maybe because ccoompiler is used for linking instead of
an fortran_compiler class.
