[SciPy-user] linalg.qr factorization so slow...

I have a 1000  x 1000  matrix. To apply a QR factorization in Matlab takes less than three seconds. however, when I do scipy.linalg.qr on the same matrix, it takes 25+ minutes.
 
Why is this? I thought they were running the same LAPACK/ATLAS/BLAS libraries underneath.
 
I am running Enthought's install on winXP; 2 GB RAM.
 
 
 
 
Please contact me if you have questions or need more information.
 
Thanks!
