Prototype

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

sbgv( const char jobz, MatrixAB& ab, MatrixBB& bb, VectorW& w,
        MatrixZ& z );

Description

sbgv (short for $FRIENDLY_NAME) provides a C++ interface to LAPACK routines SSBGV and DSBGV. sbgv computes all the eigenvalues, and optionally, the 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.

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.
