Prototype

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

gebak( const char job, const Side side, const int_t ilo,
        const int_t ihi, const VectorSCALE& scale, MatrixV& v );

Description

gebak (short for $FRIENDLY_NAME) provides a C++ interface to LAPACK routines SGEBAK, DGEBAK, CGEBAK, and ZGEBAK. gebak forms the right or left eigenvectors of a complex general matrix by backward transformation on the computed eigenvectors of the balanced matrix output by ZGEBAL.

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

Definition
