How to store results from every loop in For-Loop

Hello everyone; I want to load the whole 21 intensity images (Intensity) from the folder and find their intensity value in 6 points which I already know them.
I wrote the following program which works very well but I want to use a for loop because the number of points is not always 6.
Could you please check this code to make a for loop
for k = 1:(numel(filelist));
Intensity = imread(filelist(k).name);
P_Centro_1 = []; %1st centroid
P_Centro_1 = impixel(Intensity,(center(1,1)),(center(1,2)));
P_Centro_1 = P_Centro_1(:,1); %Intensity value
A1(:,k)= P_Centro_1;
P_Centro_2 = []; %2nd centroid
P_Centro_2 = impixel(Intensity,(center(2,1)),(center(2,2)));
P_Centro_2 = P_Centro_2(:,1);
A2(:,k)= P_Centro_2;
P_Centro_3 = []; %3rd centroid
P_Centro_3 = impixel(Intensity,(center(3,1)),(center(3,2)));
P_Centro_3 = P_Centro_3(:,1);
A3(:,k)= P_Centro_3;
P_Centro_4 = []; %4th centroid
P_Centro_4 = impixel(Intensity,(center(4,1)),(center(4,2)));
P_Centro_4 = P_Centro_4(:,1);
A4(:,k)= P_Centro_4;
P_Centro_5 = []; %5th centroid
P_Centro_5 = impixel(Intensity,(center(5,1)),(center(5,2)));
P_Centro_5 = P_Centro_5(:,1);
A5(:,k)= P_Centro_5;
P_Centro_6 = []; %6th centroid
P_Centro_6 = impixel(Intensity,(center(6,1)),(center(6,2)));
P_Centro_6 = P_Centro_6(:,1);
A6(:,k)= P_Centro_6;
end
hold on
plot(A1,'b-')
plot(A2,'c-')
plot(A3,'g-')
plot(A4,'y-')
plot(A5,'r-')
plot(A6,'m-')
hold off
So the following could be the answer but how to store the results from every for loop before going to the 2nd loop?
for k = 1:21
Intensity = imread(filelist(k).name);
for c = 1:6
P_Centro_1 = []; % list of centroids
P_Centro_1 = impixel(Intensity,(center(c,1)),(center(c,2)));
P_Centro_1 = P_Centro_1(:,1); %Intensity value
A1(:,k)= P_Centro_1;
end
end

You will probably want to use a cell array, whose elements can be pretty much everything:
C = cell(2,3);
C{1,1} = 'string';
C{1,2} = 3.1415;
C{2,1} = zeros(10,10);
C{2,3} = eye(3);

for k = 1:21
Intensity = imread(filelist(k).name);
for c = 1:6
P_Centro_1 = impixel(Intensity,(center(c,1)),(center(c,2)));
A1{k,c} = P_Centro_1(:,1); %Intensity value
end
end
