Prototype

There is one prototype of pftrs available, please see below.

pftrs( const MatrixA& a, MatrixB& b );

Description

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.
