There is one prototype of potrf
available, please see below.
potrf( MatrixA& a );
potrf
(short for $FRIENDLY_NAME)
provides a C++ interface to LAPACK routines SPOTRF, DPOTRF, CPOTRF, and
ZPOTRF. potrf
computes
the Cholesky factorization of a complex Hermitian positive definite matrix
A.
The factorization has the form A = U*H * U, if UPLO = 'U', or A = L * L*H, if UPLO = 'L', where U is an upper triangular matrix and L is lower triangular.
This is the block version of the algorithm, calling 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.
