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. This should be better behaved now in SVN. Thanks for the reports.
