我是 MATLAB 的新手。我正在尝试使用 matlab 帮助中的 S-Function 示例构建我的模型。这是 sfun_counter_cpp.cpp。源代码位于“matlabroot/simulink/src/sfun_counter_cpp.cpp”或http://www-rohan.sdsu.edu/doc/matlab/toolbox/simulink/sfg/sfun_c++2.html中。
首先，我使用“mex”命令构建 C++ S-function，如下所述：http: //www.mathworks.de/de/help/simulink/sfg/building-cs-functions.html。构建成功并创建了 sfun_counter_cpp.mexw32。之后，我创建了一个 S-Function 块，该块提供从我的框图访问 sfun_counter_cpp，单击“增量构建”并收到错误消息“OPUS MAKE：不知道如何制作'sfun_counter_cpp.cppm50'。停止。”
