There is one prototype of sbgvx
available, please see below.
sbgvx( const char jobz, const char range, MatrixAB& ab, MatrixBB& bb, MatrixQ& q, const Scalar >, const Scalar >, const int_t il, const int_t iu, const Scalar >, int_t& m, VectorW& w, MatrixZ& z, VectorIFAIL& ifail );
sbgvx (short for $FRIENDLY_NAME)
provides a C++ interface to LAPACK routines SSBGVX and DSBGVX. sbgvx computes selected eigenvalues,
and optionally, eigenvectors of a real generalized symmetric-definite
banded eigenproblem, of the form A*x=(lambda)*B*x. Here A and B are assumed
to be symmetric and banded, and B is also positive definite. Eigenvalues
and eigenvectors can be selected by specifying either all eigenvalues,
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 MatrixAB.
The type of values is obtained through the value_type
meta-function typename value_type<MatrixAB>::type. The dispatching table below illustrates
to which specific routine the code path will be generated.
Defined in header boost/numeric/bindings/lapack/driver/sbgvx.hpp.
