##### hptrs

###### Prototype

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

    hptrs( const MatrixAP& ap, const VectorIPIV& ipiv, MatrixB& b );

###### Description

`hptrs` (short for $FRIENDLY_NAME) provides a C++ interface to LAPACK routines SSPTRS, DSPTRS, CHPTRS, and ZHPTRS. `hptrs` solves a system of linear equations A*X = B with a complex Hermitian matrix A stored in packed format using the factorization A = UD*U*H or A = LD*L*H computed by ZHPTRF.

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 1.260. Dispatching of hptrs

Value type of MatrixAP | LAPACK routine
--- | ---
`float` | SSPTRS
`double` | DSPTRS
`complex<float>` | CHPTRS
`complex<double>` | ZHPTRS
