#include "petscmat.h" PetscErrorCode MatGetRowMaxAbs(Mat mat,Vec v,PetscInt idx)Logically Collective on Mat and Vec
|v||- the vector for storing the maximums|
|idx||- the indices of the column found for each row (or PETSC_NULL if not needed)|
Notes: if a row is completely empty or has only 0.0 values then the idx value for that row is 0 (the first column).
This code is only implemented for a couple of matrix formats.
