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?

Please format your code properly using the "{} Code" button. Did you see, that it is not readable?

What does "table" exactly mean in your case? We cannot guess this important detail.

sorry dude i am new to this

now here is my code

if true
%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;
disp('   f(x)    f!(x)  f(x)/f!(x)   x')
disp('======== ======== ========= =========')
for i=0:250
  fprintf('%8f %8f %8f %8f\n',f(x),f1(x),b,x)
  y=x;
  b=(f(x)/f1(x));
  x=y-b; 

        if x==y
        break
        end
end
%loop 
disp(['Root: ',num2str(x,8), ] );
    % code
but now im getting the error using fprintf after i restarted matlab
  end

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)];
