Given a rank-<code><span class='Value'>m</span></code> array of rank-<code><span class='Value'>n</span></code> arrays (requiring <code><span class='Value'>m</span><span class='Function'>≤</span><span class='Value'>n</span></code>), it will merge arrays along their first <code><span class='Value'>m</span></code> axes. For example, if the argument is a matrix of matrices representing a <a href="https://en.wikipedia.org/wiki/Block_matrix">block matrix</a>, Join will give the corresponding unblocked matrix as its result.</p> |
