Re: [Boost-users] c++: boost::multi_array - initialize a multi_array

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.

One approach is the use multi_array::data() and multi_array::num_elements() to get pointer-based iterators to the underlying raw storage: boost::multi_array<unsigned int, 1> foo( boost::extents[10] ); std::fill( foo.data(), foo.data() + foo.num_elements(), 0 ); boost::multi_array<unsigned int, 2> boo( boost::extents[10][79] ); std::fill( boo.data(), boo.data() + boo.num_elements(), 0 ); Another approach would be to use multi_array's assign member function.
