The following code sample copies a parameter value from an mxArray to the output of the S-function. In this example, the dimensions, data type, and the complexity of the parameter and the output argument are ensured to be the same. For example, if the parameter is complex, the output si...
如 std::function、 lambda 、有重载 operator() 的类和指向函数指针不是函数类型。若 T 为函数类型,则提供等于 true 的成员常量 value 。否则, value 等于false。 添加is_function 或is_function_v (C++17 起) 的特化的程序行为未定义。 模板形参 T - 要检查的类型 辅助变量模板 template< class T ...
