<li>
to find approximate solutions to underdetermined, overdetermined, or rank deficient systems of linear equations,
using <a href="#solve">solve()</a> can be considerably faster and/or more accurate
</li>
<li>
if the given matrix <i>A</i> is square-sized and seldom rank deficient, using <a href="#inv">inv()</a> or <a href="#inv_sympd">inv_sympd()</a> with the <code>inv_opts::allow_approx</code> option is faster
