i don't know why 'where' is returning matrices. if you use:

>>> idx = where(y.A > 0.5)[0] everything will work fine (I guess)

What about the second issue? Is this expected behavior?

idx array([0, 1, 2])

y

matrix([[ 0.63731308], [ 0.34282663], [ 0.53366791]])

y[idx]

matrix([[ 0.63731308], [ 0.34282663], [ 0.53366791]])

y[idx,0] matrix([[ 0.63731308, 0.34282663, 0.53366791]])

I was expecting a column vector.
