锁频环又称为自动频率控制（AFC）环，其利用反馈回路对输入频率变化进行调整，最后达到对频率的跟踪，广泛应用于雷达，卫星导航等领域对多普勒频率的跟踪。(Locked loop, also known as automatic frequency control (AFC) loop, the use of feedback loop to adjust the input frequency changes, and finally achieve frequency tracking is widely used in radar, satellite navigation and other fields on the Doppler frequency tracking.)

PSO capacitors placement in distribution system

功能：用BFGS算法求解无约束问题：min f(x) 输入：x0是初始点，fun,gfun分别是目标函数及其梯度； varargin是输入可变参数变量，简单调用bfgs时可以忽略它， 但是其他程序循环调用时将会发挥重要作用 输出：x,val分别是近似最优点和最优值，k是迭代次数。(Function: BFGS algorithm for unconstrained problem: min f (x) Input: X0 is the initial point, fun, gfun each objective function and its gradient varargin variable parameter is the input variable, it can be ignored when a simple call bfgs , but other programs will play an important role when the cycle is called output: x, val are approximate optimum and the optimal value, k is the number of iterations.)
