For loop help, initilizing seed value

heres what my problem boils down to, i want to loop over initial values for P,and output the value of P(250) but i dont know how to do it. For the following code, i get an error for "Unbalanced or unexpected parenthesis" in line 2, for P(1)

r = 3;  
for P(1) = linspace(0.1,0.9,100);
     for n = 1:250 
        P(n+1) = P(n)*r*(1-P(n)); 
      end
end
P(250)

any help would be appreciated!

Do you mean?

clear
r = 3;  
P(1)=0.1
     for n = 1:249 
      P(n+1) = P(n)*r*(1-P(n)); 
    end
P(250)

%or maybe

clear
r = 3;  
P{1}=linspace(0.1,0.9,100);
     for n = 1:249 
      P{n+1} = P{n}*r.*(1-P{n}); 
    end
P{250}

   r = 3;  
   N = 250;

   initValues = linspace(0.1,0.9,100);
   M = length(initValues);
   finalValues = zeros(M,1);
   P = zeros(N,1);
   for k = 1:M
     P(1) = initValues(k);
     for n = 1:N-1
        P(n+1) = P(n)*r*(1-P(n)); 
     end  
      finalValues(k) = P(N);
   end

   plot(initValues,finalValues);
