Boost multi_array with dynamic rank

Question

The rank (or NumDims) parameter of boost::multi_array is a std::size_t template parameter.

Is there any way to give the array a dynamic rank instead of static? I'm assuming not, looking at the code but I might have missed something.

Answer 1

That's not a feature of the library. You can emulate it, though:

• How to dynamically set dimensionality for a boost multi_array

  Here the dimensionality is not dynamic but arrays of lower dimensions are emulated by fixing the higher dimensions to 1.

• Container for boost::multi_array of same type but with different dimentionality

  The latter uses variants to store a known set of dimensionalities (with unlimited shapes).
