There is one prototype of tgsna
available, please see below.
tgsna( const char job, const char howmny, const VectorSELECT& select, const int_t n, const MatrixA& a, const MatrixB& b, const MatrixVL& vl, const MatrixVR& vr, VectorS& s, VectorDIF& dif, const int_t mm, int_t& m );
tgsna
(short for $FRIENDLY_NAME)
provides a C++ interface to LAPACK routines STGSNA, DTGSNA, CTGSNA, and
ZTGSNA. tgsna
estimates
reciprocal condition numbers for specified eigenvalues and/or eigenvectors
of a matrix pair (A, B).
(A, B) must be in generalized Schur canonical form, that is, A and B are both upper triangular.
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.
