.. function:: t = toeplitz(x)

    :param x: data
    :type x: Kx1 vector

    :return t:

    :rtype t: KxK Toeplitz matrix

Examples
----------------

::

    // Create the sequence 1, 2, 3, 4, 5 and assign it to 'x'
    x = seqa(1, 1, 5);

    // Create a diagonal-constant or Toeplitz matrix
    y = toeplitz(x);

After the code above, *y* is equal to:

::

    1  2  3  4  5
    2  1  2  3  4
    3  2  1  2  3
