Motion estimation algorithm - three step search

此为《MATLAB教程》的第八章：特征值和特征向量。该书内容翔实，深入浅出，不可多得。(This is the MATLAB Guide in Chapter VIII: Eigenvalues and eigenvectors. Book is informative, easy, hard to come by.)

说明：  调相的matlab实现，实现调相的调制解调(PM)

The proposed control law is also applied to Fractional order duffing system and to a 3D autonomous system which generates a four wing chaotic attractor to control chaos. The proposed control law makes the states of the system globally asymptotically stable and it also guarantees the system globally asymptotically in the presence of uncertainties in the states and external disturbances.
