There is one prototype of trcon
            available, please see below. 
trcon( const char norm, const MatrixA& a, Scalar > );
            trcon (short for $FRIENDLY_NAME)
            provides a C++ interface to LAPACK routines STRCON, DTRCON, CTRCON, and
            ZTRCON. trcon estimates
            the reciprocal of the condition number of a triangular matrix A, in either
            the 1-norm or the infinity-norm.
          
The norm of A is computed and an estimate is obtained for norm(inv(A)), then the reciprocal of the condition number is computed as RCOND = 1 / ( norm(A) * norm(inv(A)) ).
            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.
