<p dir="auto">This <a href="http://stackoverflow.com/questions/43712385/converting-arrayarrayfloat64-1-1-to-arrayfloat64-2-in-julia" rel="nofollow">comes up periodically</a> and it's a bit embarrassing that our official answer right now involves a inefficient splatting. We should have a function – maybe call it <code class="notranslate">stack</code>? – that efficiently does what <code class="notranslate">vcat(vec_of_vecs...)</code> does without the splatting. It should also stack in slices in different dimensions so that you can either stack slices as rows or columns, etc.</p>
