</pre><h2>Convergence test<a name="22"></a></h2><p>SVD has implemented in many numerical libraries such as LINPACK, EISPACK, and Lapack. See <a href="http://www.alglib.net/matrixops/general/svd.php">http://www.alglib.net/matrixops/general/svd.php</a>. Among them, Lapack's SVD focuses the smallest singular value. The following example is to
