课程设计代码，解决你头突的困扰，来拿吧，让老师对你刮目相看(Course design code, to solve the problem of your head, take it, let the teacher look at you.)

/*本人先后编了两次，第二次进行了改进。改进的思想主要是注意到棋盘上每一点的下一可到达点的个数 （下称为权值）不同，对于可到达点较少（权值小）的点应该先跳上去，这样后来跳的点可跳的方向就比 较多，回溯的现象就比较少，这样就可以大幅度提高速度*/-/* I have compiled twice, the second time for improvements. Improved thinking is that every point on the chessboard of the next point can be reached by the number (hereinafter referred to as the right value), For less accessible spots (small weights) should be the first point and jumped out of the way and then jump to the point of jumping on the direction of more, Looking back on the phenomenon of relatively small, we can significantly improve the speed* /

说明：  二维傅立叶变换的Matlab实现，是利用图像处理软件对给出的图像进行傅立叶变换处理。在Matlab中，函数fft2表示二维傅立叶变换，函数ifft2则表示二维傅立叶反变换。(The Fourier transform of the image)

IS015765-2 的协议，定义车载诊断系统网络层要求，提供在 CAN 数据链路层(IS011898 定义)上运行。虽说它最初设计是用在诊断系统上的，它同样适用于其它需要网络层协议 的 CAN 通信系统上。(The IS015765-2 protocol defines the vehicular diagnostic system network layer requirements provided at the CAN data link layer (IS011898) Run on definition. Although it was originally designed for diagnostic systems, it also applies to other protocols that require network layer On the CAN communication system.)
