I have a JuMP model with a mix of sparse and dense axis arrays. I find the behaviour of the indexes to be inconsistent in the sense that: eachindex(X) will give string-based indexes if X is a sparse axis array but cartesian ones for a dense array. Is there a way to convert the cartesian arrays to …

Wow thanks for that very fast and comprehensive reply.

Your suggestion of using sparse arrays with a single tuple index is very neat. I wonder if there are any performance gains from this approach vs using sparse arrays…
