MatMultTransposeAdd#

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

Synopsis#

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

Neighbor-wise Collective

Input Parameters#

  • mat - the matrix

  • v1 - the vector to be multiplied by the transpose of the matrix

  • 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 MatMultTransposeAdd(A,v1,v2,v1).
