<01>S)a2Return a new matrix of given shape and type, without initializing entries.

    Parameters
    ----------
    shape : int or tuple of int
        Shape of the empty matrix.
    dtype : data-type, optional
        Desired output data-type.
    order : {'C', 'F'}, optional
        Whether to store multi-dimensional data in row-major
        (C-style) or column-major (Fortran-style) order in
        memory.

    See Also
    --------
    empty_like, zeros

    Notes
    -----
    `empty`, unlike `zeros`, does not set the matrix values to zero,
    and may therefore be marginally faster.  On the other hand, it requires
    the user to manually set all the values in the array, and should be
    used with caution.

    Examples
    --------
    >>> import numpy.matlib
    >>> np.matlib.empty((2, 2))    # filled with random data
    matrix([[  6.76425276e-320,   9.79033856e-307], # random
            [  7.39337286e-309,   3.22135945e-309]])
    >>> np.matlib.empty((2, 2), dtype=int)
    matrix([[ 6600475,        0], # random
            [ 6586976, 22740995]])

    Matrix of ones.

    Return a matrix of given shape and type, filled with ones.

    Parameters
    ----------
    shape : {sequence of ints, int}
        Shape of the matrix
    dtype : data-type, optional
        The desired data-type for the matrix, default is np.float64.
    order : {'C', 'F'}, optional
        Whether to store matrix in C- or Fortran-contiguous order,
        default is 'C'.

    Returns
    -------
    out : matrix
        Matrix of ones of given shape, dtype, and order.

    See Also
    --------
    ones : Array of ones.
    matlib.zeros : Zero matrix.

    Notes
    -----
    If `shape` has length one i.e. ``(N,)``, or is a scalar ``N``,
    `out` becomes a single row matrix of shape ``(1,N)``.

    Examples
    --------
    >>> np.matlib.ones((2,3))
    matrix([[1.,  1.,  1.],
            [1.,  1.,  1.]])

    >>> np.matlib.ones(2)
