[PYTHON MATRIX-SIG] LinearAlgebra on Alpha.

[Rob.Hooft@embl-heidelberg.de]

I just tried some LinearAlgebra routines on DEC ALPHA, and got some
unexpected results: All zero's. What can I do to debug this?

>>> import ni,Numeric
>>> import Numeric.LinearAlgebra
>>> LA=Numeric.LinearAlgebra
>>> a=Numeric.array([[1.,0.,0.],[0.,1.,0.],[0.,0.,1.]])
>>> LA.eigenvectors(a)
( 0.  0.  0.,  0.  0.  0.
 0.  0.  0.
 0.  0.  0.)
>>> LA.singular_value_decomposition(a)
( 0.  0.  0.
 0.  0.  0.
 0.  0.  0.,  0.  0.  0.,  0.  0.  0.
 0.  0.  0.
 0.  0.  0.)
>>> LA.generalized_inverse(a) 
 0.  0.  0.
 0.  0.  0.
 0.  0.  0.
