There is one prototype of spevx
available, please see below.
spevx( const char jobz, const char range, MatrixAP& ap, const Scalar >, const Scalar >, const int_t il, const int_t iu, const Scalar >, int_t& m, VectorW& w, MatrixZ& z, VectorIFAIL& ifail );
spevx (short for $FRIENDLY_NAME)
provides a C++ interface to LAPACK routines SSPEVX and DSPEVX. spevx computes selected eigenvalues
and, optionally, eigenvectors of a real symmetric matrix A in packed
storage. Eigenvalues/vectors can be selected by specifying either a range
of values or a range of indices for the desired eigenvalues.
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.
Defined in header boost/numeric/bindings/lapack/driver/spevx.hpp.
Parameters
The definition of term 1
The definition of term 2
The definition of term 3.
Definitions may contain paragraphs.
#include <boost/numeric/bindings/lapack/driver/spevx.hpp> using namespace boost::numeric::bindings; lapack::spevx( x, y, z );
this will output
[5] 0 1 2 3 4 5
