Restores the matrix after MatGetArray() has been called.


#include "petscmat.h" 
PetscErrorCode PETSCMAT_DLLEXPORT MatRestoreArray(Mat mat,PetscScalar *v[])
Not Collective

Input Parameter

mat - the matrix
v - the location of the values

Fortran Note

This routine is used differently from Fortran, e.g.,
        Mat         mat
        PetscScalar mat_array(1)
        PetscOffset i_mat
        PetscErrorCode ierr
        call MatGetArray(mat,mat_array,i_mat,ierr)

  C  Access first local entry in matrix; note that array is
  C  treated as one dimensional
        value = mat_array(i_mat + 1)

        [... other code ...]
        call MatRestoreArray(mat,mat_array,i_mat,ierr)

See the Fortran chapter of the users manual and petsc/src/mat/examples/tests for details
