There is one prototype of larrb
available, please see below.
larrb( const int_t n, const VectorD& d, const VectorLLD& lld, const int_t ifirst, const int_t ilast, const Scalar >, const Scalar >, const int_t offset, VectorW& w, VectorWGAP& wgap, VectorWERR& werr, const Scalar >, const Scalar >, const int_t twist );
larrb (short for $FRIENDLY_NAME)
provides a C++ interface to LAPACK routines SLARRB and DLARRB. Given
the relatively robust representation(RRR) L D L^T, larrb
does "limited" bisection to refine the eigenvalues of L D L^T,
W( IFIRST-OFFSET ) through W( ILAST-OFFSET ), to more accuracy. Initial
guesses for these eigenvalues are input in W, the corresponding estimate
of the error in these guesses and their gaps are input in WERR and WGAP,
respectively. During bisection, intervals [left, right] are maintained
by storing their mid-points and semi-widths in the arrays W and WERR
respectively.
The selection of the LAPACK routine is done during compile-time, and
is determined by the type of values contained in type VectorD.
The type of values is obtained through the value_type
meta-function typename value_type<VectorD>::type. The dispatching table below illustrates
to which specific routine the code path will be generated.
