I did not know about this log determinant, thanks. But I have to say that `_` is usually used for variables we don't use, such as <pre class='brush: python'>for _ in range(5): print('Hi!') time.sleep(1) </pre> Here I had to see the doc to know it was the sign of the det. I could have guessed but I did not, the `s` in `slogdet` is probably for "sign", I see that now.

Yep the 's' stands for sign, again that's why slodget is for sign & log-determinant, You know underscore by order of the fucking PEP8 stands for non-used variable but why should she stay motionless I amma make it do something at least people can say 'Stensen Made the underscore restless HAHAHAHAHA!' BTW Stensen isn't my real name it's an alias to get in here!
