format compact
%Firstly, I converted all the images in the vector form.
whereImagesReside = 'lfwdataset';
%dir function will return the images in a structure array.
listOfImages= dir(fullfile(whereImagesReside, '*.pgm'));
%0x1 structure array is created
data = cell(size(listOfImages));
%pmg files are in 0x1 structure array.
for k=1:numel(listOfImages)
data{k}=imread(fullfile(whereImagesReside, listOfImages(k).name));
col(:,k)=data(:);
V{k}=data(:);
end
How can I get the pixel intesity of each pmg image?

It is not clear whether your images are RGB or not. If they are RGB then
intensity = cellfun(@rgb2gray, data, 'uniform', 0);
and then intensity would be a cell array in which each element is a pixel intensity array.

it is not RGB. So how can I get if it is not RGB?

Ah, looking further I see that PGM is Portable Gray Map. So every value you read in is already intensity. Your col variable will have all of the intensities stored in it.
