There is one prototype of gbcon
available, please see below.
gbcon( const char norm, const MatrixAB& ab, const VectorIPIV& ipiv, const Scalar >, Scalar > );
gbcon
(short for $FRIENDLY_NAME)
provides a C++ interface to LAPACK routines SGBCON, DGBCON, CGBCON, and
ZGBCON. gbcon
estimates
the reciprocal of the condition number of a complex general band matrix
A, in either the 1-norm or the infinity-norm, using the LU factorization
computed by ZGBTRF.
An estimate is obtained for norm(inv(A)), and the reciprocal of the condition number is computed as RCOND = 1 / ( norm(A) * 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.
