MatRestoreRow

Synopsis

#include "petscmat.h" 
PetscErrorCode MatRestoreRow(Mat mat,PetscInt row,PetscInt *ncols,const PetscInt *cols[],const PetscScalar *vals[])

Input Parameters

Notes

This routine zeros out ncols, cols, and vals. This is to prevent accidental us of the array after it has been restored. If you pass NULL, it will not zero the pointers. Use of cols or vals after MatRestoreRow is invalid.

Fortran Notes

   MatRestoreRow(matrix,row,ncols,cols,values,ierr)
      Mat     matrix (input)
      integer row    (input)
      integer ncols  (output)
      integer cols(maxcols) (output)
      double precision (or double complex) values(maxcols) output

In Fortran MatRestoreRow() MUST be called after MatGetRow() before another call to MatGetRow() can be made.
