I would presume this means that you have an image where you add mean(X,'all') to the original. The loops are not needed in Matlab. You do need to make sure that you don't overflow your data type:

super_simple_image=uint8([0 250;100 150]);
X=super_simple_image;
X=X+mean(X,'all');
%data clips to 255: [125 255;255 255]

super_simple_image=uint8([0 250;100 150]);
X=double(super_simple_image);
X=X+mean(X,'all');
%data doesn't clip: [125 375;225 275]
