Hi Stefan,

I checked it with numpy version 1.1.1 just now and the result is the same:

>>> x = N.array([0.,0,1,0,0])
>>> y1 = N.array([1.,0,0,0,0])
>>> N.correlate(x,y1, mode='full')
array([ 0.,  0.,  0.,  0.,  0.,  0.,  1.,  0.,  0.])
>>> y2 = N.array([1.,0,0,0,0,0,0])
>>> N.correlate(x,y2, mode='full')
array([ 0.,  0.,  1.,  0.,  0.,  0.,  0.,  0.,  0.,  0.,  0.])
>>> N.__version__
'1.1.1'
>>>

Best regards,
Hanno
