##### sptri

###### Prototype

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

    sptri( MatrixAP& ap, const VectorIPIV& ipiv );

###### Description

`sptri` (short for $FRIENDLY_NAME) provides a C++ interface to LAPACK routines SSPTRI, DSPTRI, CSPTRI, and ZSPTRI. `sptri` computes the inverse of a complex symmetric indefinite matrix A in packed storage using the factorization A = UD*U*T or A = LD*L*T computed by ZSPTRF.

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 1.289. Dispatching of sptri

Value type of MatrixAP | LAPACK routine
--- | ---
`float` | SSPTRI
`double` | DSPTRI
`complex<float>` | CSPTRI
`complex<double>` | ZSPTRI
