QPSK

一种精确测量间谐波的方法，可以准确检测电力系统的信号(An accurate method of measuring inter-harmonics, power system can accurately detect the signal)

构造一个空的双向栈，判断双向栈是否存在，出栈，入栈，判栈空，将栈置空，判栈满，取栈顶(Construct an empty two-way stack to determine whether there is a two-way stack, out of stack, stack, sub-stack empty, set the stack is empty, sub-stack is full, take the stack)

说明：  matlab基础教程，适合初学者的基础学习matlab。以及有一定基础者的进阶(matlab basic tutorial for beginners to learn the basis of matlab. And those who have some basic advanced)

These file simulate Time domain array beamforming and show how LHE filter reduce mmse

C-C方法计算时间延迟和嵌入维数计算Lyapunov指数计算关联维数混沌时间序列预测(The C-C Method is used to calculate the embeded dimension and Lyapunov exponents.It can be used to forcast the time series.)

BSM开环仿真程序 ，通过Matlab程序精确讲解仿真。(BSM open-loop simulation program, explain the precise simulation by Matlab program.)

Classic isotropic hardening model

matlab中同步电机在dq轴系下的建模，转子绕组短路定子绕组突然加对称电压，无阻尼绕组，自己用S函数编的，很好用的哦，适用于初学(matlab modeling of the synchronous motor in dq shaft under the rotor winding short-circuit the stator winding suddenly and symmetrical voltage damper winding S function series, very well used, suitable for beginners)

此程序能在MATLAB上实现低通滤波器，功能很强大(That this procedure can in MATLAB to achieve low-pass filter, a very powerful feature)
