Prototype

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

getri( MatrixA& a, const VectorIPIV& ipiv );

Description

getri (short for $FRIENDLY_NAME) provides a C++ interface to LAPACK routines SGETRI, DGETRI, CGETRI, and ZGETRI. getri computes the inverse of a matrix using the LU factorization computed by ZGETRF.

This method inverts U and then computes inv(A) by solving the system inv(A)*L = inv(U) for inv(A).

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.

Definition
