Comment (by cpernet):
lines 156 to 161 of hamming_code.py: this code seems very odd to me. I do
not see what you are trying to do here.
- the two branches of the if then else block are identical.
- The series of swaps being performed result in a cyclic rotation of the
first m/2 rows and the last one. Is this really what is intended?
If, as I presume, you're trying to simply flip the order of the rows,
then, try something like
{{{
H = H[::-1,:]
}}}
