Constructor & Destructor Documentation

TrilinosWrappers::BlockSparsityPattern::BlockSparsityPattern ( )

Initialize the matrix empty, that is with no memory allocated. This is useful if you want such objects as member variables in other classes. You can make the structure usable by calling the reinit() function.

TrilinosWrappers::BlockSparsityPattern::BlockSparsityPattern ( const size_type  n_rows,
const size_type  n_columns 
)

Initialize the matrix with the given number of block rows and columns. The blocks themselves are still empty, and you have to call collect_sizes() after you assign them sizes.

TrilinosWrappers::BlockSparsityPattern::BlockSparsityPattern ( const std::vector< size_type > &  row_block_sizes,
const std::vector< size_type > &  col_block_sizes 
)

Initialize the pattern with two BlockIndices for the block structures of matrix rows and columns. This function is equivalent to calling the previous constructor with the length of the two index vector and then entering the index values.

TrilinosWrappers::BlockSparsityPattern::BlockSparsityPattern ( const std::vector< Epetra_Map > &  parallel_partitioning)

Initialize the pattern with an array Epetra_Map that specifies both rows and columns of the matrix (so the final matrix will be a square matrix), where the Epetra_Map specifies the parallel distribution of the degrees of freedom on the individual block. This function is equivalent to calling the second constructor with the length of the mapping vector and then entering the index values.

TrilinosWrappers::BlockSparsityPattern::BlockSparsityPattern ( const std::vector< IndexSet > &  parallel_partitioning,
const MPI_Comm &  communicator = MPI_COMM_WORLD 
)

Initialize the pattern with an array of index sets that specifies both rows and columns of the matrix (so the final matrix will be a square matrix), where the size() of the IndexSets specifies the size of the blocks and the values in each IndexSet denotes the rows that are going to be saved in each block.

Member Function Documentation

void TrilinosWrappers::BlockSparsityPattern::reinit ( const std::vector< size_type > &  row_block_sizes,
const std::vector< size_type > &  col_block_sizes 
)

Resize the matrix to a tensor product of matrices with dimensions defined by the arguments.

The matrix will have as many block rows and columns as there are entries in the two arguments. The block at position (i,j) will have the dimensions row_block_sizes[i] times col_block_sizes[j].

void TrilinosWrappers::BlockSparsityPattern::reinit ( const std::vector< Epetra_Map > &  parallel_partitioning)

Resize the matrix to a square tensor product of matrices with parallel distribution according to the specifications in the array of Epetra_Maps.

void TrilinosWrappers::BlockSparsityPattern::reinit ( const std::vector< IndexSet > &  parallel_partitioning,
const MPI_Comm &  communicator = MPI_COMM_WORLD 
)

Resize the matrix to a square tensor product of matrices. See the constructor that takes a vector of IndexSets for details.
