This extension wraps the LAPACKE C bindings to allow access to several processes exposed by the library. Most functions work with arrays of arrays, representing rectangular matrices in row major order - so a two by two matrix [1 2; 3 4] would be array(array(1, 2), array(3, 4)) </p> </div><hr /><div class="manualnavbar" style="text-align: center;"> <div class="prev" style="text-align: left; float: left;"><a href="book.lapack.html">Lapack</a></div> <div class="next" style="text-align: right; float: right;"><a href="lapack.setup.html">Installing/Configuring</a></div> <div class="up"><a href="book.lapack.html">Lapack</a></div> <div class="home"><a href="index.html">PHP Manual</a></div> </div></body></html>
