说明：  基于EC算法的自适应波束形成技术的仿真程序，运行正确 (Simulation program of the EC algorithm-based adaptive beam forming technology, the right to run)

刚从老师实验室拿到的智能天线算法，采样矩阵求逆法，算法很精简，在DSP实现耗费时间很少，是个好算法。(just emerging from the laboratory to get teachers of smart antenna algorithms, matrix inversion sampling method, the algorithm is very concise, In DSP little time-consuming, is a good algorithm.)

说明：  This is on the power spectrum of the Matlab simulation program #use ARMA, AR, MA model and cycle map for parameter estimation system

有关同步电机的matlab仿真，非常有用 (Synchronous motor matlab simulation, very useful)
