I know there is container.Map in matlab that is equivalent to STL map in C++. How about C++ STL mulmap that could allow duplicated key values, is there equivalent one in matlab?

I could not find a direct equivalent to STL multimap in MATLAB, however, you can use cell arrays with two columns to make key-value pairs that are functionally the same.

C++:

std::multimap<std::string, int> m; 
m.insert(std::pair<std::string,int>(“key1”, 1));
m.insert(std::pair<std::string,int>(“key2”, 1));
m.insert(std::pair<std::string,int>(“key2”, 2));
m.insert(std::pair<std::string,int>(“key3”, 1));
