Using for loop for cell array

clc;clear;close all

bw = rgb2gray(imread('image_3.png'));
figure;imshow(bw);title('orginal image')

[B,~,N]=bwboundaries(bw);


obj1=B{1}; x1=obj1(:,2); y1=obj1(:,1);
area1=polyarea(x1,y1)

obj2=B{2}; x2=obj2(:,2); y2=obj2(:,1);
area2=polyarea(x2,y2)

obj3=B{3}; x3=obj3(:,2); y3=obj3(:,1);
area3=polyarea(x3,y3)

AREA=[area1 area2 area3];

[Max,name]=max(AREA(:));


MAX=B{name};

hold on
plot(MAX(:,2),MAX(:,1),"Color","r","LineWidth",2);
title(['max sphere = ',num2str(Max)])

% I want insert for loop for obj 1:3

I want insert for loop for obj 1:3

for more objects if exist

Thanks

clc;clear;close all

bw = rgb2gray(imread('image_3.png'));
figure;imshow(bw);title('orginal image')

[B,~,N]=bwboundaries(bw);


nB = numel(B);
AREA = zeros(1,nB);

for i = 1:nB
    obj = B{i};
    x = obj(:,2);
    y = obj(:,1);
    area = polyarea(x,y);
    AREA(i) = area;
end


[Max,name]=max(AREA(:));


MAX=B{name};

hold on
plot(MAX(:,2),MAX(:,1),"Color","r","LineWidth",2);
title(['max sphere = ',num2str(Max)])
