(color online) Synchronization results from simulation observation of four drive (21)–(25) and four response (26)–(29) memristor-based Chua chaotic systems: (a) (x11 + 2x21)(x31 + 5x41) and (2y11 + 4y21 + y31 + 2y41) versus t; (b) (−x12 + 2x22)(x32 + x42) and (3y12 + y22y32 + 3y42) versus t; (c) (2x13 + 2x23) (−x33x43) and (2y13 + 3y23 + 2y33y43) versus t; (d) (x14 + 2x24)(2x34 + x44) and (2y14 − 2y24 + 3y34 + y44) versus t.
