There is one prototype of potrs
            available, please see below. 
potrs( const MatrixA& a, MatrixB& b );
            potrs (short for $FRIENDLY_NAME)
            provides a C++ interface to LAPACK routines SPOTRS, DPOTRS, CPOTRS, and
            ZPOTRS. potrs 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 ZPOTRF.
          
            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.
