sbev

Prototype

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

sbev( const char jobz, MatrixAB& ab, VectorW& w, MatrixZ& z );

Description

sbev (short for $FRIENDLY_NAME) provides a C++ interface to LAPACK routines SSBEV and DSBEV. sbev computes all the eigenvalues and, optionally, eigenvectors of a real symmetric band matrix A.

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.
