@heba If you have any more questions, start a new question and then attach your data and code to read it in with the paperclip icon after you read this:

There isn't enough information to provide an answer as-is, but this probably should be posted as a new question anyway.

I'd suggest starting a new question by using the 'Ask' link at the top of the page. When you do, provide an explanation of the specifics.

what files you have (provide examples that work/don't work if possible)
attach a minimal code example that demonstrates the problem
describe the specific goals, expectations, observations

You should use the cat() function.

if your images are A and B and you want to merge them so that you get AB (A on the left with be on the right) the command looks like this:

newImg = cat(2,A,B);

If you want A on top of B:

newImg = cat(1,A,B);

I used the cat function but the new image produced is changed in color

@Vaibhav it should not change the absolute color. Are both your images RGB? Or is one gray scale? Are both in a similar value range, like 0-1 or 0-255, or 0-65535? If the ranges are way different, then one may appear a lot darker than the other. If you still have problems, attach your code and both your images and create a new discussion thread.
