Models with bipolar switching distinguishable by matlab programming memristance which raises and decreases by different polarity voltages. Models with unipolar switching behavior are distinguishable by its memristance, which can increase and reduce by matlab programming same polarity voltage. The bipolar with forgetting effect is distinguishable by its memristance which increases and reduces by matlab alternative polarity voltage, but memristance can spontaneously decrease at matlab programming same time, in spite of no voltage applied. The reversible bipolar and unipolar switching behavior , here matlab programming memristor will behave like matlab bipolar memristor at the start, but after matlab few iterations, it will turn to matlab unipolar memristor. In matlab programming same context, we use different polarization voltages, either sinusoidal or repetitive DC sweeping voltage, exploited a good way to current matlab programming various states of resistance of matlab programming memristor, and thus it shows matlab programming conduct of matlab programming four different forms of matlab memristor. Those effects reveal matlab programming richness of memristors dynamical behavior confirming matlab programming usefulness of matlab programming real model approach.
