##### 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.

Table 1.173. Dispatching of stev

Value type of VectorD | LAPACK routine
--- | ---
`float` | SSTEV
`double` | DSTEV
