Hi all, i am trying to initialize all the elements in boost::multi_array type to zero, so far, with out success. At tried using std::fill for 1-dim boost::multi_array and it worked. Once i tried std:fill on 2-dim boost::multi_array it haven't worked any more. I saw boost have #include // for 'operator+=()' #include ; libraries but i don't know if this is the correct way to initialize a 2-dim multi_array. I would like to know how to initialize a boost::multi_array in an elegant way. here is an example code of my multi_array (it pass compilation, but return an error at run time): #include <iomanip> #include "boost/multi_array.hpp" #include <iostream> namespace vec { typedef boost::multi_array uint_1d_vec_t; typedef boost::multi_array uint_2d_vec_t; typedef uint_1d_vec_t::index index_1d_t; typedef uint_2d_vec_t::index index_2d_t; } int main( ) { unsigned int num_elements, num_bits, max_runs, m; num_bits = 12; max_runs = 5000; m = 2; num_elements = ( 1 << num_bits ); int kappa = 79; vec::uint_1d_vec_t foo( boost::extents[ static_cast< vec::index_1d_t

(num_elements) ] ); vec::uint_2d_vec_t boo( boost::extents[ static_cast< vec::index_2d_t (num_elements) ][ static_cast< vec::index_2d_t >(kappa) ] );

std::fill( foo.begin() , foo.end() , 0); std::fill( boo.begin()->begin() , boo.end()->end() , 0); std::cout << "Done" << std::endl; return EXIT_SUCCESS; } any suggestion is welcome regards
