#include "petscmat.h" PetscErrorCode MatGetRowMax(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 (optional) |
Notes: The result of this call are the same as if one converted the matrix to dense format and found the minimum value in each row (i.e. the implicit zeros are counted as zeros).
This code is only implemented for a couple of matrix formats.
