要将C MEX S-Function合并到模型中,请从Simulink 库浏览器中拖动 S-Function模块。同样,要将 2 级 MATLAB S-Function合并到模型中,请将 2 级 MATLAB S-Function模块拖到模型中。 打开“模块参数”对话框,并在“S-Function名称”字段中指定S-Function名称,以便为 S-Function模块提供功能。例如,键入 timestwo ...
Can you guess what this function does? Multiple functions per file 🚿🚿🚿 It is a common and false prejudice that MATLAB cannot cope with several functions per file. The truth is: There may be more than one function in a file, but just the first one in the file will be visible ...
