There is one prototype of spcon
available, please see below.
spcon( const MatrixAP& ap, const VectorIPIV& ipiv, const Scalar >, Scalar > );
spcon
(short for $FRIENDLY_NAME)
provides a C++ interface to LAPACK routines SSPCON, DSPCON, CSPCON, and
ZSPCON. spcon
estimates
the reciprocal of the condition number (in the 1-norm) of a complex symmetric
packed matrix A using the factorization A = UD*U*T
or A = LD*L*T computed by ZSPTRF.
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 MatrixAP
.
The type of values is obtained through the value_type
meta-function typename value_type<MatrixAP>::type
. The dispatching table below illustrates
to which specific routine the code path will be generated.
