[Boost-users] Large boost::multi_array Problem

Hi, I have the following problem, I make a boost::multi_array of size X by X. I initialise this using the following line typedef boost::multi_array array_type; array_type D(boost::extents[num_vertices][num_vertices]); This works fine up to a size of 5000 x 5000 then my program crashes at the definition stage due to memory requirements. I am assuming the boost::extents call stops my program creating a multi array of a size bigger than 5000 x 5000. However in certain situations I need a bigger 2D array, any thoughts on how I can achieve this? Adam
