Plot image in 2d plain and apply operations like translation/rotation and reflection

I want to read an image on matlab and on 2d plain perform changes of its coordinates as I would have done on a graph
img = imread('img.png');
sz = size(img);
imshow(img);
I am very new to matlab and do not understand much too. I know that imread will get 3d matrix. First 2 with original values
and the last for RGB.
Those are color values and I do not thin that can be used to apply rotation or translation
Below is the example oof what I actually want to do.

rgbImage = imread('peppers.png');
title('Original')
nexttile
imshow(rgbImage);
img2 = imrotate(rgbImage, 90);
title('Rotated')
nexttile
imshow(img2);
img3 = flipud(rgbImage);
nexttile
imshow(img3);
title('Flipped top-to-bottom about horizontal axis')
