   :description "A Clojure library designed to manipulate sparse *arrays* - multi-dimensional spaces accessed by indices, but containing arbitrary values rather than just numbers. For sparse spaces which contain numbers only, you're better to use a *sparse matrix* library, for example [clojure.core.matrix](https://mikera.github.io/core.matrix/)."
