We use matrices for generating the LDPC decoder core:
  http://www.opencores.org/projects/cf_ldpc/

The binary sparce matrics describe the bipartite graph between message 
nodes and check nodes, as well as decoding operations.  The 
Confluence source code shows how matrices can be used to generate 
HDL:
