There is one prototype of hpgvx
available, please see below.
hpgvx( const int_t itype, const char jobz, const char range, MatrixAP& ap, MatrixBP& bp, const Scalar >, const Scalar >, const int_t il, const int_t iu, const Scalar >, int_t& m, VectorW& w, MatrixZ& z, VectorIFAIL& ifail );
hpgvx (short for $FRIENDLY_NAME)
provides a C++ interface to LAPACK routines SSPGVX, DSPGVX, CHPGVX, and
ZHPGVX. hpgvx computes
selected eigenvalues and, optionally, 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.
Eigenvalues and eigenvectors can be selected by specifying either 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 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.
