There is one prototype of hegv
available, please see below.
hegv( const int_t itype, const char jobz, MatrixA& a, MatrixB& b, VectorW& w );
hegv
(short for $FRIENDLY_NAME)
provides a C++ interface to LAPACK routines SSYGV, DSYGV, CHEGV, and
ZHEGV. hegv
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 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 MatrixA
.
The type of values is obtained through the value_type
meta-function typename value_type<MatrixA>::type
. The dispatching table below illustrates
to which specific routine the code path will be generated.
