MATLAB: How to concatenate GRAYSCALE and RGB images

catconcatenateMATLAB

I'm trying to concatenate a graysacale and rgb image but it shows error.
This is the code
>> A = imread('bird.jpg');
>> B = rgb2gray(A);
>> imshow(A),imshow(B);
>> C = cat(2,A,B);
Error using cat
Dimensions of arrays being concatenated are not consistent.
Can someone help me out?
I want this effect which is shown in given image

Hi, If just want to stitch them you can try using the montage() function of matlab.
Hope this helps!
