Could you be more specific about which functions cause the hang?
linalg functions seem to work fine with NaNs here (I didn't update cvs
array([[ 1. , 2. ],
[ nan, 4. ]])
array([ nan+0.j, nan+0.j])
array([[ nan, nan],
[ nan, nan]])
array([ nan, nan])
array([[ 1.00000000e+000, 2.00000000e+000],
[ inf, 4.00000000e+000]])
array([ 1., 0.])
array([[ 0. , 0.5],
[ 0. , 0. ]])
I am using ATLAS-3.2.1 here.
