There is one prototype of pstrf
available, please see below.
pstrf( MatrixA& a, VectorPIV& piv, int_t& rank, const Scalar > );
pstrf
(short for $FRIENDLY_NAME)
provides a C++ interface to LAPACK routines SPSTRF, DPSTRF, CPSTRF, and
ZPSTRF. pstrf
computes
the Cholesky factorization with complete pivoting of a complex Hermitian
positive semidefinite matrix A.
The factorization has the form P' * A * P = U' * U , if UPLO = 'U', P' * A * P = L * L', if UPLO = 'L', where U is an upper triangular matrix and L is lower triangular, and P is stored as vector PIV.
This algorithm does not attempt to check that A is positive semidefinite. This version of the algorithm calls level 3 BLAS.
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.
