How to use for loop

Hello, I'm supposed to make a code that prompts the user to enter a positive real number to 1 decimal place. I should prompt the user 10 times. This was the code I used.

user_input = fprintf('%.1f', input('Enter a positive real number'));

for i = 1:10
    if user_input <= 0
        user_input = fprintf('%.1f', input('Enter a positive real number'));
    end
end

user_input = fprintf('%.1f\n', input('Enter a positive real number\n'));
for i = 1:9 %first input outside the loop;so 9 more inputs
    if user_input >= 0
        user_input = fprintf('%.1f\n', input('Enter a positive real number\n'));
    end
end

user_input = fprintf('%.1f\n', input('Enter a positive real number'));
count = 0 ; 
while count <= 10
    if user_input >= 0
        count = count+1 ;
        user_input = fprintf('%.1f\n', input('Enter a positive real number'));
    end
end
