Detailed Description

Function Documentation

symbol_init_adddofs()

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
