##### spev

###### Prototype

There is one prototype of `spev` available, please see below.

    spev( const char jobz, MatrixAP& ap, VectorW& w, MatrixZ& z );

###### Description

`spev` (short for $FRIENDLY_NAME) provides a C++ interface to LAPACK routines SSPEV and DSPEV. `spev` computes all the eigenvalues and, optionally, eigenvectors of a real symmetric matrix A in packed storage.

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

Value type of MatrixAP | LAPACK routine
--- | ---
`float` | SSPEV
`double` | DSPEV

###### Definition

###### Complexity

###### Example

    #include <boost/numeric/bindings/lapack/driver/spev.hpp>
    using namespace boost::numeric::bindings;

    lapack::spev( x, y, z );

this will output

    [5] 0 1 2 3 4 5
