在 MATLAB Online 中打开

t0 = randperm(100,1) ;   % give some value 
tol = 10^-3 ;            % mention the accuracy you want 
for i = 1:10000
    % find your output here 
    t1 = randperm(100,1) ;    % random value for demo  
    if abs(t0-t1) < tol 
        break 
    else
        t0 = t1 ; 
    end
end
[t0 t1 i]
ans = 1×3
