Hi to all. Sorry for my English. I'm trying to use a boost::multi_array as a private member of a class. How I can specifying the number of elements for every dimensions into the constructor? #include <iostream> #include "boost/multi_array.hpp" using namespace std; typedef boost::multi_array table; class X { public: X(); ~X(){}; // ... void do_something(); private: table tab; boost::array dims; }; X::X() { dims = {{3, 5}}; // fails table(dims); } int main() { X x; x.do_something(); system("PAUSE"); return 0; } Thanks to all.
