Hi Putra,
In the "I' file, 65536 x 3, here '3' is for the RGB values, it doesn't signify that is has 3 different images stored in it. If you really want all the .jpg files in same matrix, then you can use the following code
A = imread('owl.0.jpg');
B = imread('owl.1.jpg');
C = imread('owl.2.jpg');
I = [A B C];

Hi Putra, Actually here we can use imread function:
img1=imread('owl.0.jpg');
img2=imread('owl.1.jpg');
img3=imread('owl.2.jpg');
Now as you want to concatenate the matrix , we can do the same as follows:
IMG1 = [img1 img2 img3] %340 x 1536 x 3
%or
IMG=[img1;img2;img3] % 1020 x 512 x 3
Here you can access individual images as follows:
img1=IMG(1);
img2=IMT(2);
img3=IMG(3);
For more understanding , you can refer here :Concatenating Matrices
