Simulink can pass N-D array data to custom code functions in C Caller blocks, and receive data from such blocks. When you do so, you must specify the correct array layout to achieve the intended results. See Default function array layout and Exception by function. For examples of the use...

宁以pass-by-reference-to-const 替换 pass-by-value (前者通常更高效、避免切割问题(slicing problem),但不适用于内置类型、STL迭代器、函数对象) 必须返回对象时,别妄想返回其 reference(绝不返回 pointer 或 reference 指向一个 local stack 对象,或返回 reference 指向一个 heap-allocated 对象,或返回 pointer ...
使用引用调用(call-by-reference)的一个原因是可以对参数进行完美转发。它有自己的规则 template<typename T> void passR(T&& arg) { } std::string s = "hi"; passR(s); // OK: T deduced as std::string& (also the type of arg) passR(std::string("hi")); // OK: T deduced as std:...

You'll also need to update the calls to placement new to pass the new type (for example, by using static_cast<my_type> to convert from the integer value) and update the definition of new and delete to cast back to the integer type. You don't need to use an enum for this; a ...
