The procedures are that Mex file is compiled with C++ or Fortran, Matlab interpreter transfers and implements dynamic connect function, install Mex file editor, debug and compile Mex file, transfer Mex file to realize read-write of serial port.

• 文件法用Matlab应用程序接口实现,其步骤:用C++/Fortran编写Mex文件,Matlab解释器调用并执行动态链接函数; 安装Mex文件编辑器对Mex文件调试与编译;
