<p>I don't know where else we might use <code>inplace_transpose()</code>. Do you think we should just inline it here instead of adding new files in <code>arma_extend/</code>? I don't think this contribution will go back upstream, which is usually what <code>arma_extend</code> is for (backporting new functionality, or preparing new stuff to submit upstream).</p>
