永磁同步电动机的异步启动matlab程序模型 (Permanent magnet synchronous motor to start the asynchronous process model matlab)

it is the code for linear block code

FFT简称为快速傅里叶变换，是DTF处理的一般实现方法，一维距离成像就是对差拍信号进行FFT变换，变换所得到的幅值图像横坐标为距离信息，纵坐标为幅值信息，通过一维仿真，我们可以看到目标距离相对应的幅值信息。(FFT referred to as fast Fourier transform, is DTF processing general method, a d imaging is difference from pat signal FFT transform)

利用MATLAB读取excel邻接矩阵数据，利用自带函数dist对路网共193个节点循环，求解任意两点间最短路径长度，输出结果是矩阵形式(a good way to calculate the shortest path between two points)
