Prototype

There is one prototype of sterf available, please see below.

sterf( const int_t n, VectorD& d, VectorE& e );

Description

sterf (short for $FRIENDLY_NAME) provides a C++ interface to LAPACK routines SSTERF and DSTERF. sterf computes all eigenvalues of a symmetric tridiagonal matrix using the Pal-Walker-Kahan variant of the QL or QR algorithm.

The selection of the LAPACK routine is done during compile-time, and is determined by the type of values contained in type VectorD. The type of values is obtained through the value_type meta-function typename value_type<VectorD>::type. The dispatching table below illustrates to which specific routine the code path will be generated.

Definition

Defined in header boost/numeric/bindings/lapack/computational/sterf.hpp.

Example

#include <boost/numeric/bindings/lapack/computational/sterf.hpp>
using namespace boost::numeric::bindings;

lapack::sterf( x, y, z );

this will output
