Examples

>>>x=np.matrix(np.arange(12).reshape((3,4)));xmatrix([[ 0,  1,  2,  3],        [ 4,  5,  6,  7],        [ 8,  9, 10, 11]])>>>y=x[0];ymatrix([[0, 1, 2, 3]])>>>(x==y)matrix([[ True,  True,  True,  True],        [False, False, False, False],        [False, False, False, False]], dtype=bool)>>>(x==y).all()False>>>(x==y).all(0)matrix([[False, False, False, False]], dtype=bool)>>>(x==y).all(1)matrix([[ True],        [False],        [False]], dtype=bool)
