Creating objects of classes in std namespace, including custom classes.

Smart pointer semantics. Only std::shared_ptr is supported. MATLAB does not support operator overloads, move semantics, and the member functions in the class definition of the smart pointer which might restrict their effectiveness. Instead, a std::shared_ptr<T> behaves as type T in MATLAB. Type T can be passed as input for std::shared_ptr<T>, and type T is received as output for std::shared_ptr<T>.

Namespace aliases. Use original namespace name instead.

Passing nullptr to C++ functions or data members.

Certain class methods that have MATLAB names are not supported. These methods are eq, ne, lt, gt, le, and ge.
