对matlab的入门知识进行讲述，适用于初学者使用(Introductory knowledge of matlab to talk, for beginners)

说明：  matlab下的有用的时频分析工具箱，包括各类调频信号的生成，频率相位提取(matlab useful under the time-frequency analysis toolbox, including the generation of various types of FM signals, frequency-phase extraction)

说明：  黄金分割法求极小值 功能：用黄金分割法求f(x)在区间[a,b]上的近似极小值。当且仅当f(x)在[a,b]上为单峰时次方法适用 (Golden section method for the minimum functions: golden section method used for f (x) in the interval [a, b] on the approximate minimum. If and only if f (x) in [a, b] for the single-peak method can be applied at times)

关于MATLAB的经典教程，百看不厌，十分经典。(classic tutorial about matlab,and it is suitable fot the fresh man.)

有一个3阶对象，要求使用继电自整定方法对其实施自适应PID控制。 要求： 1、选择采样时间0.1s，把对象离散化。 2、加继电（开关）控制，测量对象的Tc,Kc。 3、利用ZIEGLER-NICHOLS 公式表，确定PID参数。 4、实现闭环控制。 5、根据调节效果，修正PID参数。 (A 3-order object, requires the use of relay self-tuning PID control methods on the implementation of adaptive. Requirements: 1, select the sampling time 0.1s, the discrete objects. 2, plus relay (switch) control, measurement object Tc, Kc. 3, using ZIEGLER-NICHOLS formula table, determine the PID parameters. 4, closed loop. 5, according to moderating effect, the amendment PID parameters.)
