There is an example of how to use the LDPC encode/decode with AWGN channel model in files .ldpc_decode.m and .GFqldpc_decode.m. There are a few parity check matrices available in the code but you can use other matrices provided you have enough memory to load them. I suggest checking out matrices in Alist format available on David MacKay s web site.You will need to have access to a MEX compiler to be able to use a few functions written in C.
