6889,Initialise multi_array with a given value,Andrew Morris <andy@…>,Ronald Garcia,"The multi-array only allows users to initialise all elements to a default constructed T(). That may not be desirable if you would like a different value, either for performance reasons or because the type does not support default initialisation. For example:


{{{
#include <vector>
#include <boost/multi_array.hpp>

struct no_default
{
    explicit no_default(int i) {}
};

int main()
{
    std::vector<no_default> v(10, no_default(3));
    boost::multi_array<no_default, 3> m(boost::extents[10][10][10]); // won't compile
}
}}}

Offering constructors that accept a value to be used to initialise the elements would be the easiest fix. This would also align with std::vector usage.",Feature Requests,new,To Be Determined,multi_array,Boost 1.49.0,Problem,,,
