How Can I merge R,G,B Components of an image into a single RGB image ?

I am using 'V4L2 Video Capture' block for interfacing my Raspberrypi Camera with my laptop. I need a single multidimensional signal instead of three separate R, G, B components. Please suggest me any solution for this. It should be compatible with code generation. Thanks in advance.

I also tried 'cat', but it was giving me errors while using code generation.

R= rand(200) ;
G = rand(200) ;
B = rand(200) ;
I = cat(3,R,G,B) ;
imshow(I)
