There is one prototype of hpgv
available, please see below.
hpgv( const int_t itype, const char jobz, MatrixAP& ap, MatrixBP& bp, VectorW& w, MatrixZ& z );
hpgv
(short for $FRIENDLY_NAME)
provides a C++ interface to LAPACK routines SSPGV, DSPGV, CHPGV, and
ZHPGV. hpgv
computes
all the eigenvalues and, optionally, the eigenvectors of a complex generalized
Hermitian-definite eigenproblem, of the form A*x(lambda)*B*x,
A*Bx
(lambda)*x, or B*A*x=(lambda)*x. Here A and B are assumed
to be Hermitian, stored in packed format, 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 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.
