There is one prototype of sytri
            available, please see below. 
sytri( MatrixA& a, const VectorIPIV& ipiv );
            sytri (short for $FRIENDLY_NAME)
            provides a C++ interface to LAPACK routines SSYTRI, DSYTRI, CSYTRI, and
            ZSYTRI. sytri computes
            the inverse of a complex symmetric indefinite matrix A using the factorization
            A = UD*U*T or A = LD*L*T
            computed by ZSYTRF.
          
            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.
