I have a code here:

%% Get the dimensions of the image
Namelist = cell(length(filelist), 1);
for i = 1:length(filelist)
    imagename = filelist(i).name;
    Namelist{i, 1} = filelist(i).name;
    I = imread ([newimagepath, '/', imagename]);
    
    [y x z] = size(I);
    T = table(x, y, z)
    
end

I have let's say 100 images (I), how can I have the (x, y, z) for each image be put into the table? Currently, when I run the code, the table ends up being 1 row, with the x, y, z values for the last image in the loop.

Thank you in advance!!

%% Get the dimensions of the image
Namelist = cell(length(filelist), 1);
N = length(filelist) ; 
S = zeros(N,3) ; 
for i = 1:N
    imagename = filelist(i).name;
    Namelist{i, 1} = filelist(i).name;
    I = imread ([newimagepath, '/', imagename]);
    
    S(i,:) = size(I) ; 
        
end
x = S(:,1) ; y = S(:,2) ; z = S(:,3) ; 
T = table(x,y,z)
