用matlab软件实现画一个凸轮的形状，并作出它的位移，速度，加速度曲线。(Matlab software used to draw a cam shape, and make its displacement, velocity and acceleration curves.)

在科研中，大量时间花在统计年鉴的搜集上，例如找《中国城市统计年鉴》中2000多个市，要对分散的八个城市群找对应的数据，如果每次筛选会花费大量时间，如果做好excel表头，把对应的城市写上去会在多个文件多个工作组查找满足要求的数据，直接按需要保存成excel，进行后续分析。(In the research, the amount of time spent on the Statistical Yearbook of the collection, for example, to find " China City Statistical Yearbook" in more than 2000 cities and want to find a group of eight cities scattered corresponding data, if each screening will spend a lot of time, If you do excel header, the corresponding write up the city will look to meet the requirements of data in multiple files multiple workgroups, saved directly as needed to excel, for subsequent analysis.)
