MatMultHermitianTransposeAdd

Computes \(v3 = v2 + A^H * v1\).

Synopsis

#include "petscmat.h" 
PetscErrorCode MatMultHermitianTransposeAdd(Mat mat, Vec v1, Vec v2, Vec v3)

Neighbor-wise Collective

Input Parameters

• mat - the matrix

• v1 - the vector to be multiplied by the Hermitian transpose

• v2 - the vector to be added to the result

Output Parameter

• v3 - the result

Note

The vectors v1 and v3 cannot be the same. I.e., one cannot call MatMultHermitianTransposeAdd(A,v1,v2,v1).
