I've been doing this for some time and have started to feel some pain in the maintenance area. Wrapper functions are starting to be duplicated between wrapper modules, and classes depending on wrappers are importing functions that they'll never call. But most of all, building out and maintain...

template <typenameF>function&operator=(std::reference_wrapper<F>)noexcept; 可以理解为模板赋值函数的特化。没有相应的构造函数。 默认构造函数、nullptr_t构造函数、nullptr_t拷贝赋值函数都将std::function对象置空。当std::function对象没有保存任何函数对象时,operatorbool()返回false,与nullptr_t调用operator==...
手写C MEX S-Function---这种方式提供了最大的编程自由度,你可以使用C MEX S-Function来实现你的算法,也可以写一个wrapper S-Function,调用已经存在的C,C++,Fortran代码。使用这种方式编写一个新的S-Function需要对于S-Function API的了解,如果你写的S-Function要产生内联代码,还需要熟悉TLC。 S...
