[Numpy-discussion] QR algorithms in Python

[James G A. <jam...@ph...>]

Hi,
I'm looking for a QR algorithm that can decompose complex matrices. The=20
LinearAlgebra package from Numeric doesn't seem to have it. SciPy's linal=
g=20
package is still on the way, so I can't use that either. Matfunc's QR=20
decomposition only works for real matrices. This problem came up two year=
s=20
ago on this same discussion panel, and Konrad Hinsen recommended that the=
=20
user download PyLapack from ftp://dirac.cnrs-orleans.fr/pub/
I cannot compile PyLapack because I get this problem:

[analytis@toomey Modules]$ python2 compile.py
Copy Misc/Makefile.pre.in from the Python distribution
to this directory and try again.
make: Makefile.pre.in: No such file or directory
make: *** No rule to make target `Makefile.pre.in'.  Stop.
make: *** No targets specified and no makefile found.  Stop.
[analytis@toomey Modules]$

I think the Makefile searched for is one from an earlier version of Numer=
ic=20
(the tar file is 2yrs old). Any suggestions?
Cheers,
James
