##### tptri

###### Prototype

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

    tptri( MatrixAP& ap );

###### Description

`tptri` (short for $FRIENDLY_NAME) provides a C++ interface to LAPACK routines STPTRI, DTPTRI, CTPTRI, and ZTPTRI. `tptri` computes the inverse of a complex upper or lower triangular matrix A stored in packed format.

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 1.302. Dispatching of tptri

Value type of MatrixAP | LAPACK routine
--- | ---
`float` | STPTRI
`double` | DTPTRI
`complex<float>` | CTPTRI
`complex<double>` | ZTPTRI
