MATLAB: Vector output from a for loop

for loophelpif statementvector

Hello everyone,
I have an hourly temperature data which covers 8760 values inside a vector. The TMP shows the temperature values however the values below in the code is just for example since i can't put 8760 values here.
I want to get PGRED results as a vector output too. However, when i run the code, although it calculates PGRED values for all TMP values, i get an answer only for the last TMP value which is 36 in this case. My question is, how can i get all the PGRED answers inside 1 vector.
Thank you for your help in advance.
for TMP =[12, 3, 36]
         
    if TMP < 9 
    PGRED=0
   
elseif 9<=TMP & TMP<10
    PGRED= TMP-9
    
elseif 10<=TMP & TMP<28
    PGRED= 1
    
elseif 28<=TMP & TMP<40
    PGRED= -0.083*TMP + 3.33
   
else 40 >= TMP
    PGRED=0
  
    end   
end

TMP =[12, 3, 36];
PGRED=zeros(size(TMP));
for ii=1:length(TMP)
         
    if TMP(ii) < 9 
    PGRED(ii)=0;
   
elseif 9<=TMP(ii) && TMP(ii)<10
    PGRED(ii)= TMP(ii)-9;
    
elseif 10<=TMP(ii) && TMP(ii)<28
    PGRED(ii)= 1;
    
elseif 28<=TMP(ii) && TMP(ii)<40
    PGRED(ii)= -0.083*TMP(ii) + 3.33;
   
else %40 >= TMP(ii) % this condition is not required. Just give a default condition.
    PGRED(ii)=0;
  
    end   
end
