Something is wrong with the Inverse class

[ted-python]

for (int i=jj; i<L; i++)
 {
 if(AA[i][jj]==1)//==1
 {
 LOW[kk]=i;
 kk++;
 }
 }

I am wondering whether you can use the AA[i][jj]>=-1 in the code
When I compare the result of your decoder and the original source, there are mistakes. So it can not decode successfully.
