MatGetRowMinAbs#
Gets the minimum value (in absolute value) of each row of the matrix
Synopsis#
#include "petscmat.h"
PetscErrorCode MatGetRowMinAbs(Mat mat, Vec v, PetscInt idx[])
Logically Collective
Input Parameter#
mat - the matrix
Output Parameters#
v - the vector for storing the minimums
idx - the indices of the column found for each row (or
NULLif 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.
