There is one prototype of hecon
available, please see below.
hecon( const MatrixA& a, const VectorIPIV& ipiv, const Scalar >, Scalar > );
hecon
(short for $FRIENDLY_NAME)
provides a C++ interface to LAPACK routines SSYCON, DSYCON, CHECON, and
ZHECON. hecon
estimates
the reciprocal of the condition number of a complex Hermitian matrix
A using the factorization A = UD*U*H
or A = LD*L*H computed by ZHETRF.
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 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.
