%encode:
%coded = tpc_encode2d(msg,M);   
%coded: out coded stream whose length is code_L;
%msg: in msg stream whose length is msg_L;
%M: the parameter which determine the msg_L and code_L of extended hamming
%code;

%decode:
%[decod llr_all]=tpc_decode2d(r,M,iter_num, delta);
%decod:out decoded stream whose length is msg_L;
%llr_all:output extrinic llr of the decoder; notes:it is the extrinic llr;
%r:in coded out coded stream whose length is code_L;
%M:must be the same to the coder;
%iter_num:the number of iterative processing:;
%delta:the parameter of decoder.4 is recommend, 3 and 5 for reference.
