Given a rank-`m` array of rank-`n` arrays (requiring `m≤n`), it will merge arrays along their first `m` axes. For example, if the argument is a matrix of matrices representing a [block matrix](https://en.wikipedia.org/wiki/Block_matrix), Join will give the corresponding unblocked matrix as its result. -- cgit v1.2.3
