Hi all,

The different results disappeared misteriously  !
Something must happened to numpy/scipy
between

ATLAS 3.6.0
>>> scipy.__version__
'0.5.0.2147'
>>> numpy.__version__
'1.0b2.dev2951'
>>>

and

ATLAS 3.6.0
>>> numpy.__version__
'1.0b2.dev3005'
>>> scipy.__version__
'0.5.0.2158'
>>>         

Note that ATLAS has been retained unchanged !!!
