MatRestoreRowIJF90

restores the compressed row storage i and j indices for the local rows of a sparse matrix obtained with MatGetRowIJF90()

Synopsis

MatRestoreRowIJF90(Mat A, PetscInt shift, PetscBool symmetric, PetscBool inodecompressed, PetscInt n, {PetscInt, pointer :: ia(:)}, {PetscInt, pointer :: ja(:)}, PetscBool done,integer ierr)

Not Collective

Input Parameters

• A - the matrix

• shift - 0 or 1 indicating we want the indices starting at 0 or 1

• symmetric - PETSC_TRUE or PETSC_FALSE indicating the matrix data structure should be symmetrized inodecompressed - PETSC_TRUE or PETSC_FALSE indicating if the nonzero structure of the inodes or the nonzero elements is wanted. For MATBAIJ matrices the compressed version is always used.

• n - number of local rows in the (possibly compressed) matrix

• ia - the row pointers; that is ia[0] = 0, ia[row] = ia[row-1] + number of elements in that row of the matrix

• ja - the column indices

• done - indicates if the routine actually worked and returned appropriate ia[] and ja[] arrays; callers are responsible for handling the case when done == PETSC_FALSE and ia and ja are not set
