function [out] = iteration(N)
if N<1
error('Input must be >0')
end
x(1)=4;
for k=1:N
x(k+1)=1+(0.5*sin(k)); %#ok<AGROW>
end
disp('The elements stored in x are:')
disp(x)
fun=@(x)1+(0.5*sin(x));
xz=fzero(fun,2);
disp('The zero given by xz is:')
disp(xz)
out=abs(xz-x);
disp('v=')
disp(out)
Hi, Above is my code so far however it doesn't work for the fzero part and shows v as NaN and also for the last part, I have no idea what to do
Any suggestions are appreciated :)

What needs more input arguments? It’s not at all clear.

I do apologise for being unclear, but I've figured out what I was doing wrong there, I've edited the question for the second part

You have to call your function with one input, e.g.
iteration(20)
