I have imported an image and I require there to be a solid green image of the same dimensions directly above the imported image. How would I go about doing this? I have attempted using patch but to no success.

directly above the imported image??
Question is not clear? What result you are expecting? May be you require one green image (plane) having size equal to the processed image. Clarify ?

Essentially I require 2 images, one of a solid green square and beneath it my imported image. I have attached an image of it

I1 = imread('peppers.png') ;
[nx,ny,nz] = size(I1) ;
I2 = zeros(nx,ny,nz) ;
I2(:,:,2) = 255 ;
I12 = vertcat(I2,I1) ;
imshow(I12)
