Comment:
Helloooooooo Frederic !
Thank you for this patch. I personally find it clearer, and at least it
should be faster. I also added a small commit to this patch (sorry, I just
cannot not remove a 'if' when I see a way `:-P`).
I still have a few questions : is it really the *inverse* of the Ihara
function (as the documentation claims) or is that a mistake ?
- If it is can you fix it in the docstring and in the function index at
the top of the file
- If not, shouldn't it appear in the function's name too ?
I cannot check from the Wikipedia page that the polynomial you implemented
is indeed what it should be. Of course this is mainly because I don't get
a word of what this polynomial represents, but I would like to check the
correction anyway `^^;`
Could you help me a bit with that ? `:-P`
Thaaaaaaaaanks !
Nathann
