how do you make the results of a loop into table?

here is my code
%start
syms 'x';
%to be able to input x
fun= input ('Enter function in terms of "x":');
%user input
f=inline(fun);
z=diff(f(x));
%differentiate in terms of x
f1=inline(z);
xo=input('enter initial value "xo":');
%input user initial value
x=xo;
for i=0:1000
y=x;
x=y-(f(x)/f1(x)) ;
if x==y
break
end
end
%loop
disp(['Root: ',num2str(x), ] );
disp('In the beginning, God said that the four dimensional divergence of an antisymmetric second rank tensor equals zero and there was light.');
%output up to 7 decimal places
m=input('Do you want to continue, Y/N [Y]:','s');
if m=='Y'
clc
newtonrap
else
clc
end
%ask to exit or continue
so, I want to take the answers of 'x','y',f(x) and f1(x) within the loop an make a table out of it. is that possible?

I don't see any table - that is a very specific special kind of variable. Looks like you're just printing a table to the command line without using a "table" variable. You forgot to give us the inputs you entered into this program. I, for one, will wait until you give us that.

Like Jan wrote, you should format your code and explain "table" in order to geta better answer. I only can guess you want a 2D-array:
Before the for loop:
your_table = zeros(1001,4)
in the for loop:
your_table(i,:) = [x y f(x) f1(x)];
