1.新建sfunction的C语言文件 打开simulink,点击User-Defined Functions里面的S-Function Exampleso这个里面有多个语言版本的模板,有C, C++, Ada, Fortran和M语言的版本,其实都大同小异,只要了解儿个函数就很容易使用了。选择C语言的版 本:从S-function模块中选择C-file S-functions里面的Basic C-MEX templateo打开...
matlab/simulink中PSO模块调用通过S-function 很多联合仿真中需要调用PSO并,可通过simuli/nk中用户自定义函数里的S-function实现PSO的调用。 使用S-function模板对PSO的m文件进行调用 在sinulink中通过三个正弦波模拟输入,用示波器看输出,如图 其中s-function定义如下: 里面的sfuntest可根据matlab中自带的sfun... ...
