Example #1

File: Tsqr_CacheBlocker.hpp Project: haripandey/trilinos

    MatrixViewType
    split_bottom_block (MatrixViewType& A, const bool contiguous_cache_blocks) const
    {
      typedef typename MatrixViewType::ordinal_type ordinal_type;
      const ordinal_type nrows_bottom = 
	strategy_.bottom_block_split_nrows (A.nrows(), ncols(), 
					    nrows_cache_block());
      // split_bottom() modifies A
      return A.split_bottom (nrows_bottom, contiguous_cache_blocks);
    }

Example #2

    MatrixViewType
    split_bottom_block (MatrixViewType& A, const bool contiguous_cache_blocks) const
    {
      typedef typename MatrixViewType::ordinal_type ordinal_type;
      // Ignore the number of columns in A, since we want to block all
      // matrices using the same cache blocking strategy.
      const ordinal_type nrows_bottom = 
	strategy_.bottom_block_split_nrows (A.nrows(), ncols(), 
					    nrows_cache_block());
      // split_bottom() sets A to A_rest, and returns A_bot.
      return A.split_bottom (nrows_bottom, contiguous_cache_blocks);
    }
