| decode | ldpc_decoder | Subroutine | Iteratively decode array of LLR (or LAPPRs) based on syndrome |
| decode_flood | ldpc_decoder | Subroutine | Iteratively decode array of LLR (or LAPPRs) based on syndrome |
| destructor | ldpc_decoder | Subroutine | Destructor method for the TDecoder object It will just deallocate whatever was allocated. |
| destructor | ldpc_edge_list | Subroutine | Should be called automatically |
| edge_to_node_convert_table | ldpc_decoder | Subroutine | Build node-to-node connection list from node-to-edge and edge-to-other-node |

| f_plus_box | ldpc_decoder | Function | Box-plus sum |
| invert_table | ldpc_decoder | Subroutine | Create an array which contains, in each location, the list of edges connected to the node corresponding to that location |
| llr_to_word | ldpc_decoder | Function | Binarize the LLRs (or LAPPRs) |
| print_decoder | ldpc_decoder | Subroutine | |
| process_cnode | ldpc_decoder | Subroutine | Variable node A Posteriori Probability (APP) processing function |
| process_cnode_flood | ldpc_decoder | Subroutine | Generic processing function, it works both for variable- and for check- nodes - for variable nodes, f_plus_kind is a simple addition routine - for check nodes, f_plus_kind can be: + the "box plus" for exact message passing + the min abs with sign product for the min-sum algorithm + whatever you want for your approximation |
