stev

Prototype

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

stev( const char jobz, const int_t n, VectorD& d,
        VectorE& e, MatrixZ& z );

Description

stev (short for $FRIENDLY_NAME) provides a C++ interface to LAPACK routines SSTEV and DSTEV. stev computes all eigenvalues and, optionally, eigenvectors of a real symmetric tridiagonal matrix A.

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