Kamali, you have to explain better what it is you want to do. As commented you already have the pixels in an array. It's the my_image array

pixel = cell(1,rows);
ctr = 1;
for R=1:rows
for C=1:columns
pixel{ctr}=my_image(R,C);
disp (R)
end
ctr = ctr+1;
end
celldisp(pixel)
[pixel{:}] % double array

ACTUALLY my input is a 256X320 but i get only a single row with 256 elements in it.
my_image =imread('football.jpg');
my_image=rgb2gray(my_image);
[rows,columns,depth]=size(my_image);
pixel = cell(1,rows);
ctr = 1;
for R=1:rows
for C=1:columns
pixel{ctr}=my_image(R,C);
end
ctr = ctr+1;
end
celldisp(pixel)
disp ([pixel{:}]); % double array
what are the necessary changes in it?
thanks in advance.

The pixel values are already stored in my_image and do not need to be stored again .

What data type do you need as output? What array size do you need as output? What difference do you intend between "pixel values" that you want stored, compared to what is already in my_array ?

For the information of other users, In this file exchange - https://www.mathworks.com/matlabcentral/fileexchange/72535-image-to-c-c-array-converter, I have written a script to generate an array from an image. I convert the input image to monochrome and store the pixel values in hex format in a different file. It could be modified to suit your needs.
Hope that helps.
