dataset_folder='D:\Project\resize\';
file_name=dir(fullfile(dataset_folder,'*.jpg'));
total_images=numel(file_name);
for n=1:total_images
original=fullfile(dataset_folder, file_name(n).name);
x=imread(original);
r=x(250,250,1);
g=x(250,250,2);
b=x(250,250,3);
ph_factor =(double(g)/double(b))/double(r);
ph=sprintf('Red-%d Green-%d Blue-%d ph factor-%f',r,g,b,ph_factor);
disp(ph);
end
when i see the value of r,g,b and ph_factor only the value of last image is stored.
how can i store the values of all images for every iteration in the corresponding same variable?
Please help me

dataset_folder='D:\Project\resize\';
file_name=dir(fullfile(dataset_folder,'*.jpg'));
total_images=numel(file_name);
r = zeros(250,250,total_images) ;
g = zeros(250,250,total_images) ;
b = zeros(250,250,total_images) ;
ph_factor = zeros(250,250,total_images) ;
for n=1:total_images
original=fullfile(dataset_folder, file_name(n).name);
x=imread(original);
r(:,:,n)=x(250,250,1);
g(:,:,n)=x(250,250,2);
b(:,:,n)=x(250,250,3);
ph_factor(:,:,n) =(double(g)/double(b))/double(r);
ph=sprintf('Red-%d Green-%d Blue-%d ph factor-%f',r,g,b,ph_factor);
disp(ph);
end
