I have two fine packages for you:
- Arrays exposes a common array interface, with multiple different implementations that you can try if the default performance characteristics are not to your liking. (The two built-in implementations are a map-based implementation and an
:arrays-based implementation.)
This is probably perfect for your needs, although the last time I had time to work on it I was unable to write proper documentation and tests, so these are still lacking.
If you need to do more mathematical stuff with them:
- Tensor gives you one-dimensional vectors, two-dimensional matrices and n-dimensional tensors, and defines many common operations on them. Tensor stores these in a sparse format, which may or may not be suited well to your problem domain.
Tensor is very stable and greatly documented and tested.
