MATLAB: How to display all values of an iteration

iteration

hi so this is my code, currently it only displays the root and the number of bisections, but I need it to also display the value of each iteration, I'm not sure how to do this. Any help would be much appreciated!

for i = 1:100
    xc = (x1 + x2)/2;
    if f(x1)*f(xc)<0
        x2 = xc;
    else
        x1 = xc;
    end
    disp(['x1 = ',num2str(x1),',' ' x2 = ',num2str(x2)])
    if abs(f(x1))<1e-6
        break
    end
end

you can also use fprintf() instead of disp().

hope this helps.

After the first box, you write

deltaT = epsilon + 1; % so that the while loop is entered
while deltaT >= epsilon
    % put code of the second box here
    deltaT = % add equation for new updated value of deltaT
 end

MATLAB: Calculate mean using while and iteration

So you want to calculate these values?

xn(1)=mean(b(a>0.5 & a<1.5));
xn(2)=mean(b(a>1.5 & a<2.5));
xn(3)=mean(b(a>2.5 & a<3.5));
etc?

You don't need a while loop for that:

a=[0.5 0.6 0.9 1.0 1.1 1.2 1.5 1.8 2.1 2.3 2.4 2.6 2.9 3.0 3.12 3.15 3.16 3.18];
b=[1.8 1.5 1.8 1.5 1.4 1.4 1.6 1.2 1.2 1.3 1.5 1.8 2.0 3.0 3.2 1.9 1.7 2.2];
del=0.5;
xn=zeros(1,ceil(max(a-del)));
for k=1:size(xn,2)
    xn(k)=mean(b(a>(k-del) & a<(k+del)));
end
