I have to combine two grayscale image with a RGB image. While combining I am facing the issue of different size of matrices and I do not want to use 'imtile' function. How can I approach these task?

If you need to edge-concatenate two images, you will need to match their corresponding geometry. At that point, you can use basic concatenation (e.g. cat() or []).
In order to make their geometry compatible, you can:
  • resize one or both images (see imresize())
  • crop the larger image (see imcrop())
  • pad the smaller image (see padarray())
In order to make monochrome and RGB images match on dim3, you can either
  • expand the single-channel image (see repmat())
  • collapse the multichannel image (see rgb2gray())
That said, i'm only assuming you want to concatenate based on the mention of imtile(). As you don't want to use imtile(), I'm reluctant to recommend other tools that can directly do similar things; after all, if imtile() doesn't do what you want, maybe they don't either. If by "combine", you mean something other than concatenation, you'll have to clarify.

yes,sir,may be use imresize to make them to same size,and cat them to one matrix
if possible,please upload your image files to do some analysis
