There is one prototype of pbcon
available, please see below.
pbcon( const MatrixAB& ab, const Scalar >, Scalar > );
pbcon
(short for $FRIENDLY_NAME)
provides a C++ interface to LAPACK routines SPBCON, DPBCON, CPBCON, and
ZPBCON. pbcon
estimates
the reciprocal of the condition number (in the 1-norm) of a complex Hermitian
positive definite band matrix using the Cholesky factorization A = U**H*U
or A = LL*H computed by ZPBTRF.
An estimate is obtained for norm(inv(A)), and the reciprocal of the condition number is computed as RCOND = 1 / (ANORM * norm(inv(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.
