[Numpy-discussion] Apparently non-deterministic behaviour of complex array multiplication

[kneil]

Hi Olivier, 
Sorry for the late reply - I have been on travel.  
I have encountered the error in two separate cases; when I was using numpy
arrays, and when I was using numpy matrices.
In the case of a numpy array (Y), the operation is:
dot(Y,Y.conj().transpose())
and in the case of a matrix,  with X=asmatrix(Y) and then the operation is:
X*X.H
-Karl
