matlab7.0的ppt教材，教授一些基本且常用的命令，帮助初学者掌握matlab的使用。(matlab7.0 the ppt textbooks, professors, some of the basic and commonly used commands, helping beginners to master the use of matlab.)

基于干扰观测器的PID控制 通过PID控制对存在干扰的被控对象的仿真(Based on disturbance observer PID control PID control by the existence of the object and interference simulation)

this matlab function finds peaks of a plot. it takes a coordinate matrix as an input. also removes redundent peaks (for instance, in case of a step plot, it finds one peak)
