I solved this problem but the file didn't run, the codes in the editor are:

function [s,ea,i]=SqRoot(a,eps,maxit)
i = 0;
s = a/2;
ea = 100;
while(1)
    sold = s;
    s= (s+a/s)/2;
    i = i+1;
    if s ~= 0, ea=abs((s - sold)/s)*100; end
    if ea <= eps | i>= maxit, break, end
end

‘Did you see the attached photo?’

No, because no photo was attached.

a_arg  = rand();

maxit_arg = randi([10,500]);
[s_ans, ea_ans, i_ans] = Student(a_arg, eps_arg, maxit_arg)

Your code runs for me, and produces the correct result:

a = 50;                                             % Argument
maxit = 100;                                        % Argument
i = 0;
s = a/2;
ea = 100;
while(1)
    sold = s;
    s= (s+a/s)/2;
    i = i+1;
    if s ~= 0, ea=abs((s - sold)/s)*100; end
    if ea <= eps || i>= maxit, break, end
end
