# numpy.matrix.prod

`matrix.``prod`(axis=None, dtype=None, out=None)

  Return the product of the array elements over the given axis.

  Refer to `prod` for full documentation.

  See also

  `prod`, `ndarray.prod`

  Notes

  Same as `ndarray.prod`, except, where that returns an `ndarray`, this returns a `matrix` object instead.

  Examples

      >>> x = np.matrix(np.arange(12).reshape((3,4))); x
      matrix([[ 0,  1,  2,  3],
              [ 4,  5,  6,  7],
              [ 8,  9, 10, 11]])
      >>> x.prod()
      0
      >>> x.prod(0)
      matrix([[  0,  45, 120, 231]])
      >>> x.prod(1)
      matrix([[   0],
              [ 840],
              [7920]])
