There is one prototype of pocon
available, please see below.
pocon( const MatrixA& a, const Scalar >, Scalar > );
pocon (short for $FRIENDLY_NAME)
provides a C++ interface to LAPACK routines SPOCON, DPOCON, CPOCON, and
ZPOCON. pocon estimates
the reciprocal of the condition number (in the 1-norm) of a complex Hermitian
positive definite matrix using the Cholesky factorization A = U**H*U
or A = LL*H computed by ZPOTRF.
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.
