Prototype

There is one prototype of pptri available, please see below.

pptri( MatrixAP& ap );

Description

pptri (short for $FRIENDLY_NAME) provides a C++ interface to LAPACK routines SPPTRI, DPPTRI, CPPTRI, and ZPPTRI. pptri 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 ZPPTRF.

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.

Definition
