Hi, I am Paula, I am student and I am working with Olena. I have a doubt: I want to use an array of vectors in Olena, which I'm able to define it, but not to insert the values and display them to see the results. Maybe I'm defining it wrong: fun::i2v::array< std::vector<int> >prueba; Is it well defined? How can I do to insert the values? How can I do to display them to see the results? Thank you. Best regards. Paula.
