Prototype

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

trsna( const char job, const char howmny, const VectorSELECT& select,
        const MatrixT& t, const MatrixVL& vl, const MatrixVR& vr, VectorS& s,
        VectorSEP& sep, const int_t mm, int_t& m,
        const int_t ldwork );

Description

trsna (short for $FRIENDLY_NAME) provides a C++ interface to LAPACK routines STRSNA, DTRSNA, CTRSNA, and ZTRSNA. trsna estimates reciprocal condition numbers for specified eigenvalues and/or right eigenvectors of a complex upper triangular matrix T (or of any matrix QT*Q*H with Q unitary).

The selection of the LAPACK routine is done during compile-time, and is determined by the type of values contained in type VectorSELECT. The type of values is obtained through the value_type meta-function typename value_type<VectorSELECT>::type. The dispatching table below illustrates to which specific routine the code path will be generated.
