storing changing values in a loop ????

I have created this loop to find the fitting polynomials nth order (1 to 10).Output ''p'' is the coefficients of the polynomials. I have found ''d''(results of polynomials) and i would like to plot them vs given x values.

problem is that i must find d values which are 2,5,9,14,20,27,35,44,54,65 in order of outputs. how can i organise my outputs like that ??????

    if true
    % clear all 
clc
x=(-1:0.1:1);
y=[27.84,21.82,17.10,13.40,10.51,8.235,6.454,5.059,3.965,3.108,2.436,1.909,1.497,1.173,0.9194,0.7206,0.5648,0.4427,0.3470,0.2720,0.2132];
i=0;
sum=0;
imax=9;
while   i<=imax
        i=i+1
        p=polyfit(x,y,i);
        sum=0;
        sumnew=0;
        t=1;
        while   t<=numel(p)
                sumnew=(x.^(t-1))*p(t);
                sum=sum+sumnew;
                d=sum
                t=t+1;
        end
end
  end

i get the output like this

if true
  % i =
   1
d =

for ii = 10:-1:1
   p{ii} = polyfit(x,y,ii);

thank you for your help ! but this code gives 10 'd' matrix with only 10 columns. I my solution i had 21 values in a d matrix. I dont know how to rearrange it for that ? (d must have 21 values in matrix so that i cant plot vs 21 x values)
