##### heev

###### Prototype

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

    heev( const char jobz, MatrixA& a, VectorW& w );

###### Description

`heev` (short for $FRIENDLY_NAME) provides a C++ interface to LAPACK routines SSYEV, DSYEV, CHEEV, and ZHEEV. `heev` computes all eigenvalues and, optionally, eigenvectors of a complex Hermitian matrix A.

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

Table 1.160. Dispatching of heev

Value type of MatrixA | LAPACK routine
--- | ---
`float` | SSYEV
`double` | DSYEV
`complex<float>` | CHEEV
`complex<double>` | ZHEEV
