only 10 lines.
% Want to swap pixel at (x1,y1) in image with the pixel at (x2,y2)
I = imread('face.jpg');
x1 = 25;
y1 = 25;
x2 = 25;
y2 = 370;

% Get pixel data from image
pixel1 = I(y1, x1, :);
pixel2 = I(y2, x2, :);

% Swap pixels
I(y1, x1, :) = pixel2;
I(y2, x2, :) = pixel1;
imshow(I);

Yes, the code provided is a complete and executable MATLAB program. It reads an image, swaps the pixels at coordinates (x1, y1) and (x2, y2), and then displays the modified image. However, there's a small issue in the code: the indexing for pixel access should start from 1 instead of 0. So, if you're using 0-based indexing, you might need to adjust the pixel coordinates accordingly.
