Prototype

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

spev( const char jobz, MatrixAP& ap, VectorW& w, MatrixZ& z );

Description

spev (short for $FRIENDLY_NAME) provides a C++ interface to LAPACK routines SSPEV and DSPEV. spev computes all the eigenvalues and, optionally, eigenvectors of a real symmetric matrix A in packed storage.

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

Definition

Defined in header boost/numeric/bindings/lapack/driver/spev.hpp.

Example

#include <boost/numeric/bindings/lapack/driver/spev.hpp>
using namespace boost::numeric::bindings;

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

this will output

[5] 0 1 2 3 4 5
