Re: [Boost-users] [multi-array] Extracting dimension information from a multi-array

Ryan McConnehey writes:

Do you have an example of how shape() works?  The shape method isn't used in any of the multi-array tutorials.  Also, the reference material says the shape method returns a list of "NumDims" but the return signature specifies a "const size_type *" is returned.  How is "const size_type *" a list of dimension?

Since it is not a container, you will need to use the ::dimensionality to see how far to iterate this bare pointer. e.g. to put it into a bounded ublas vector vector: const static std::size_t rank = ublas::multi_array::dimensionality; //Or just 3 in this case... Showing you this could work in generic code ublas::bounded_vector dims; std::copy(var.shape(), var.shape() + rank, dims.begin());
