There is one prototype of pftrs
available, please see below.
pftrs( const MatrixA& a, MatrixB& b );
pftrs
(short for $FRIENDLY_NAME)
provides a C++ interface to LAPACK routines SPFTRS, DPFTRS, CPFTRS, and
ZPFTRS. pftrs
solves
a system of linear equations AX = B with a Hermitian
positive definite matrix A using the Cholesky factorization A = U*H*U
or A = LL*H computed by ZPFTRF.
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.
