Hi,
Has anyone written any quadratic programming algoritm?
If so, please let me now.

We have written a wapper around

  COPL_QP Computational Optimization Program Library:
          Convex Quadratic Programming

from ftp://dollar.biz.uiowa.edu/pub/yyye/. I had to make some minor
changes to the qp program to make it work under WindowsNT, but it does
now. I have seen the library working under NT, solaris 2.5.1, solaris
2.7 and a Linux system. I don't now where to put the tar file, but when
you are interested, I could send you a copy of the library, installable
with a recent distutils version.

Greetings

Berthold

Hi all,

Please let me know if this is the wrong mailing list for this question:

I'm running red hat linux 6.2 and have used rpms to install the numpy,
lapack, and blas packages.  How do I get numpy to use the versions of lapack
and blas I've installed?  Thanks.

You can't do it with the NumPy RPMs, which use the C versions.
So you must get the NumPy source code distribution and compile it
yourself. Before compiling it, edit the file "Setup" such that
the line starting with "lapack_lite" reads

lapack_lite -I./Include Src/lapack_litemodule.c -llapack -lblas -lg2c -lm

The compile and install according to the instructions.

Konrad,
These instructions rely on the old way of making numpy.
The new way would involve making corresponding changes to setup.py
I intend to do this as the default soon as I have had numerous requests for
it.

Is it possible with Distutils to use LAPACK if it's installed and
the C versions otherwise? That should make everybody happy.

Konrad.
