Reversing the axis direction reverses the plot as well.
I = imread('https://www.mathworks.com/matlabcentral/answers/uploaded_files/625258/Captura.PNG');
figure
imshow(I)
title('Original')
figure
imshow(I)
Ax = gca;
Ax.XDir = 'reverse';
title('X-Axis Direction Reversed')
.

A = imread('ngc6543a.jpg');
imshow(A)
B = fliplr(A);
imshow(B)
