    :param x: data
    :type x: scalar or NxK matrix

    :return str_int: or string array containing the string representation of the elements of x.

    :rtype str_int: string

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

::

  // Set x
  x = 4;

  // Convert integer to string
  str_int = itos(x);

  // Print results
  print "x = " x;
  print "str_int = " str_int;

::

  x =
