What you want to do and what you have done?

Answer 1

[Yona]

you need to find a function of X from your equation for your example X^3-2X=1

you get X(X^2-2)=1 and then X=1/(X^2-2)

so build a function that calculate f(x)=1/(X^2-2)

in loop you can do

x=0.5;
for i=1:n
  x=1/(x^2-2)
end

It better to put better rule then do N iteration (for example, the change in x is lower then eps)
