##### hpev

###### Prototype

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

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

###### Description

`hpev` (short for $FRIENDLY_NAME) provides a C++ interface to LAPACK routines SSPEV, DSPEV, CHPEV, and ZHPEV. `hpev` computes all the eigenvalues and, optionally, eigenvectors of a complex Hermitian matrix 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.

Table 1.164. Dispatching of hpev

Value type of MatrixAP | LAPACK routine
--- | ---
`float` | SSPEV
`double` | DSPEV
`complex<float>` | CHPEV
`complex<double>` | ZHPEV
