I meant the submatrix of G - I used something like that in the decode procedure in another post, just replacing A.transpose() with a random matrix. I looked at the C.decode (for C in the original post), and it does something different - it corrects the errors. Perhaps, the better name for it would be C.correct ? Also, perhaps, just simple linsolve can be used (in my decode) if it exists in Sage and works for overdetermined systems of linear equations.
