a=0;

b=2;

E0=[];

% since you know what size e and n will have you can define them here alrdy

[e,n]=deal(zeros(8,1))

f=@(x)exp(-exp(-x))-x; %the nonlinear function

for i=3:10

% index starts at 1

e(i-2)=10^-i;

n(i-2)=ceil(log(b-a)-log(e(i-2))/log(2));

hold on

axis([10^-10 10^-3 0 12])

grid on

% points can still be plottet

plot(e(i-2),n(i-2),'.')

% why i again, you used i inprevious loop

% dont use same variable for index of a loop in a loop

for j=1:n

c=(a+b)/2;

if f(c)*f(a)<0

b=c;

else

a=c;

end

end

end

% plot lines between the points

plot(e,n)

x=linspace(0,2*pi,100);

plot(x,sin(x))

plot(e, n, 'r.-', 'LineWidth', 2, 'MarkerSize', 15);
