There is one prototype of hbgst
available, please see below.
hbgst( const char vect, MatrixAB& ab, const MatrixBB& bb, MatrixX& x );
hbgst
(short for $FRIENDLY_NAME)
provides a C++ interface to LAPACK routines SSBGST, DSBGST, CHBGST, and
ZHBGST. hbgst
reduces
a complex Hermitian-definite banded generalized eigenproblem A*x = lambda*B*x
to standard form C*y = lambda*y, such that C has the same bandwidth as
A.
B must have been previously factorized as S*H*S by ZPBSTF, using a split Cholesky factorization. A is overwritten by C = X*HA*X, where X = S*(-1)*Q and Q is a unitary matrix chosen to preserve the bandwidth of 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.
