# numpy.matrix.all

`matrix.``all`(axis=None, out=None)

  Test whether all matrix elements along a given axis evaluate to True.

  Parameters : | See `numpy.all` for complete descriptions :

  See also

  `numpy.all`

  Notes

  This is the same as `ndarray.all`, but it returns a `matrix` object.

  Examples

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