## Function Documentation

 static void symbol_init_adddofs ( const pastix_graph_t * graph, const pastix_order_t * order, symbol_matrix_t * symbptr )
inlinestatic

Add a dof array to the symbol matrix if any.

If the dof parameter is variadic, then a permuted version of the initial dof array is constructed to match the symbol matrix that is working the permuted matrix A.

Parameters
 [in] graph The original graph of the matrix [in] order The ordering structure describing the permutation of the unknowns in the compressed form. [in,out] symbptr The symbol structure to which dof array must be added.

## ◆ symbol_expand_find_schurcblk()

 static pastix_int_t symbol_expand_find_schurcblk ( const symbol_matrix_t * symbptr )
inlinestatic

Compute the index of the first cblk belonging to the Schur complement.

Parameters
 [in,out] symbptr The symbol structure pointer in which to find the schur.
Returns
The index of the first cblk belonging to the Schur complement.

## ◆ symbol_expand_var()

 static void symbol_expand_var ( symbol_matrix_t * symbptr )
inlinestatic

Expand the symbol matrix structure when the dof are variadic.

Parameters
 [in,out] symbptr The symbol structure to expand. On entry, the information is based on the compressed graph. On exit, the information are expanded to the size of the expanded matrix.

## ◆ symbol_expand_fix()

 static void symbol_expand_fix ( symbol_matrix_t * symbptr )
inlinestatic

Expand the symbol matrix structure when the dof are constant.

Parameters
 [in,out] symbptr The symbol structure to expand. On entry, the information is based on the compressed graph. On exit, the information are expanded to the size of the expanded matrix.
