New extension proposal: PHP LAPACK (linear algebra)

Hi all, I've wrapped a few functions from the LAPACK* linear algebra library (new BSD licensed) in a simple PHP extension. Code is on github - https://github.com/ianbarber/php-lapack Would love to hear any feedback/suggestions on the code (and also the API if anyone has experience with the library). Currently is designed as a series of static functions, as the underlying library is a series of optimised routines, so it looks like: <?php $a = array( array( 7.52, -1.10, -7.95, 1.08 ), array(-0.76, 0.62, 9.34, -7.10 ), array( 5.13, 6.62, -5.66, 0.87 ), array(-4.75, 8.52, 5.75, 5.30 ), array( 1.33, 4.91, -5.49, -3.52 ), array(-2.40, -6.77, 2.34, 3.95 ), ); $result = Lapack::singularValues($a); foreach($result as $k => $r) { foreach($r as $ik => $ir) { $result[$k][$ik] = round($ir, 2); } } var_dump($result); ?> --EXPECT-- array(1) { [0]=> array(4) { [0]=> float(18.37) [1]=> float(13.63) [2]=> float(10.85) [3]=> float(4.49) } } The aim is to work through the most useful functions (generally ones which solve complete classes of problems), and potentially expose some of the lower level functions if there is demand. I'm not shooting for a super optimised version for large data sets, just something workable for day to day LA requirements. Thanks! Ian *http://www.netlib.org/lapack/
