Hmm. One would think that diag() would accept a flatiter
object, but it does not. Shouldn't it??
But anyway, you can squeeze x:
>>> x
matrix([[ 0.46474951],
[ 0.0688041 ],
[ 0.61141623]])
>>> y=N.diag(N.squeeze(x.A))
>>> y
array([[ 0.46474951, 0. , 0. ],
[ 0. , 0.0688041 , 0. ],
[ 0. , 0. , 0.61141623]])
