(PECL lapack >= 0.1.0)
LAPACK is written in Fortran 90 and provides routines for solving systems of simultaneous linear equations, least-squares solutions of linear systems of equations, eigenvalue problems, and singular value problems. 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)).
All of the functions are called statically, for example $eig = Lapack::eigenvalues($a);
$a
[, array $left
[, array $right
]] )$n
)$a
, array $b
)$a
