I'm currently working on a numerical project that uses boost.python, and since we already had boost as a dependency we've begun using boost/multi_array_ref to simplify multi-dimensional array handling in our code. I was rather surprised when the following code fragment spit out pages of errors when I tried to compile it: float* data = (float*) malloc(nx*ny*sizeof(float)); [...] boost::multi_array_ref<float, 2> xy(data, boost::extents[nx][ny]); xy = 0.; // errors out here Looking through the docs I realized that operator= isn't even mentioned, so perhaps I shouldn't have been surprised. It is rather unfortunate, though, that such a statement isn't allowed. (Unless, of course, I'm doing something wrong, which is completely possible.) Is there any plan to add such functionality in the future, or would it make more sense for us to switch to a different library (blitz++ or something similar)?
