Flip image from one side to another

Once you upload a picture into matlab is there anyway that you can take the one half, for example the left half and flip it onto the right side while leaving the original left side? I want to create the mirror image of one side and put it on the other

It's not entirely clear what you're asking, but try flipdim to flip an image; use horzcat to join two images. Here's an example you can run:

I = imread('peppers.png'); 

subplot(2,2,1) 
imshow(I)
title 'original image' 

% Flip left/right: 
Ir = flipdim(I,2); 

subplot(2,2,2) 
imshow(Ir)
title 'flipped image'

% Join the original and flipped images: 
IIr = horzcat(I,Ir); 

subplot(2,2,3:4) 
imshow(IIr)
title 'joined images'
