What if we represent the $|x|$ like this: $|x| = \sqrt{x^2}$. Then at least we can find the derivative.

comment Why does this algorithm work?
No indexes like $i$ and $j$ in the $p_{ij}^{(n)}$ formula? So every element of the matrix has the same value?

Sorry, but a question about $p_{ij}^{(n)}$ what is it? element of the matrix $P^n$? And what are $A$ and $B$ some numbers right?
