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]graphThe original graph of the matrix
[in]orderThe ordering structure describing the permutation of the unknowns in the compressed form.
[in,out]symbptrThe 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]symbptrThe 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]symbptrThe 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]symbptrThe 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.
