presents two orders of a Koch curve. The zero order is the initiator (straight line) with the initiator points (A,B); the components of the Cartesian coordinates of this order forming the (1 × n) matrix are (x a , x b ) and (y a , y b ). The first order Koch curve consisted of 5 principal points (2 initiators points (1 and 5) and 3 generated points (2, 3 and 4)); the components of the Cartesian coordinates of this order forming the (1 × n) matrix are (x1, x2, x3, x4, x5) and (y1, y2, y3, y4, y5).
