用MATLAB写的体彩七位数计算每位上各个数字出现次数的小程序(Written using MATLAB Ticai 7 calculated for each different figure on the number of occurrences of small programs)

利用矩量法计算正方形金属柱体的散射，并计算柱体的RCS(The use of moment method to calculate the scattering of a square metal cylinders)

EMD的程序要用到matlab的时频工具箱 matlab的工具箱的安装步骤： 1.解压下载的文件包，将tft/mfile复制到matlab的toolbox文件夹下 2.建立搜索路径，matlab->file->Set Path->Add Folder ->选择mfile文件夹复制到matlab的toolbox的路径->save->close 3.测试是否建立搜索路径成功，在matlab命令窗口打入：which fmsin 返回的结果是你放mfile的正确路径说明建立搜索路径成功。此时就完成了安装工具包的工作。(EMD program to use when the frequency of matlab toolbox matlab toolbox installation steps: Unzip the downloaded file package, copy tft/mfile to the toolbox matlab file folder 2 established the search path, matlab-> file-> Set Path-> Add Folder -> Select mfile folder to the toolbox matlab path-> save-> close 3 test whether to establish a successful search path in matlab command window enter: which fmsin The result returned is the correct path you put mfile instructions to establish a successful search path. This time to complete the installation kit work.)
