As I mentioned, x(i) should become xnorm(i) and rho(i) should equal rho(i+1). I suspect that this is the problem, that somehow the order of the operations regarding rho is making it so that the relative error doesn't change. I have tried taking rho(i) out of the loop and calculating rho(1) but that did not seem to help either. I've been struggling with these problems for a few days so the help is really appreciated.
================
For these issues, it would be recommendable to get familiar with setting breakpoints and other MATLAB debugging tools, as the others have recommended.
In case it's useful, I gave someone a small demo of some of the debugging tools here:
