Thanks for the quick reply. I'll try upgrading. Best, Ph. On Monday 04 May 2009 04:21:29 pm Stéfan van der Walt wrote:

Hi Philipp

If I see this correctly, my SciPy version is 0.6.0; running on 64bit Suse 11.

SciPy 0.6 is quite old, and it is likely that the problem was fixed in the mean time.

On SciPy 0.7 I see:

In [31]: u,s,v = linalg.svd(m)

In [32]: u Out[32]: array([[-0.70710678, 0. , -0.70710678, 0. ], [-0.70710678, 0. , 0.70710678, 0. ], [ 0. , -0.70710678, 0. , -0.70710678], [ 0. , -0.70710678, 0. , 0.70710678]])

In [33]: s Out[33]: array([ 2., 2., 0., 0.])

In [34]: v Out[34]: array([[-0.70710678, -0.70710678, -0. , -0. ], [-0. , -0. , -0.70710678, -0.70710678], [-0.70710678, 0.70710678, 0. , 0. ], [ 0. , 0. , -0.70710678, 0.70710678]])
