##### potri

###### Prototype

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

    potri( MatrixA& a );

###### Description

`potri` (short for $FRIENDLY_NAME) provides a C++ interface to LAPACK routines SPOTRI, DPOTRI, CPOTRI, and ZPOTRI. `potri` computes the inverse of a complex Hermitian positive definite matrix A using the Cholesky factorization A = U**H*U or A = LL*H computed by ZPOTRF.

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 1.273. Dispatching of potri

Value type of MatrixA | LAPACK routine
--- | ---
`float` | SPOTRI
`double` | DPOTRI
`complex<float>` | CPOTRI
`complex<double>` | ZPOTRI
