comment Mathematica: Solve function problem
@Simon Is there a way to use that functions described in that link? I have downloaded that file and tried evaluate that functions but my Mathematica doesn't recognize them.

@J. M. What do you mean by "reluctance to help Mathematica give you what you want"? And what is not that smart? I didn't get it. I want independent from human solution, so that you don't need to copy past something.

So you mean that I have to use mouse and copy past expressions by myself? You just want to say that my problem can't be solved in Mathematica? By the way I checked the Maxima system, the same problem there.

How can I split them in Mathematica?

I have updated the answer, please look at the EDIT1 and EDIT2.

I didn't define them as something. They are also not fixed values. I just entered them as you see above, in the form x[i], y[i]. As indexed variables

comment Representation of this function using a single formula without conditions
Sorry, my mistake, will edit it now. $G = G(x)$

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?
