Need help to debug code

function [x1] = tutorial1(x0,nMax,tol)
x0 = 1.5;
nMax = 15;
tol = 1e-4;

% for loop acting continously for 15 iterations 
for i = 1:nMax
    fx0= (x0).^3-3.^(x0)+1;
    differentialx0=3.*(x0.^2) - 3.^x0.*log(3);
    %function f(x0)respectively
    x1 = x0 -fx0./differentialx0;

if abs(x1-x0)<tol
    break
end 
    x0 = x1; 
    
fprintf('Iteration = %d, x0 = %.4f, x1 = %.4f, fx1 = %.4f\n',i,x0,x1);
end 



% Sample output code for monitoring (this should be included in your loop structure.

There is no coding error.

function [x1]=tutorial1(x0,nMax,tol)
% for loop acting continously for 15 iterations 
for i = 1:nMax
    fx0= (x0).^3-3.^(x0)+1;
    differentialx0=3.*(x0.^2) - 3.^x0.*log(3);
    %function f(x0)respectively
    x1 = x0 -fx0./differentialx0;
if abs(x1-x0)<tol
    break
end 
    x0 = x1; 
fprintf('Iteration = %d, x0 = %.4f, x1 = %.4f, fx1 = %.4f\n',i,x0,x1);
end

% Your code as per definition/requirements

end 

Save the function as Matlab function file "tutorial1.m" and call it from command promt or a other main script. Please note during call you have to pass the input arguments, as specified in the function file.
