I have two matrices: A & B ... I want to combine them so that every element will be near the other one's corresponding element. For example something like C matrix.
A=[1,2;3,4]
B=[5,6;7,8]
C=[15,26; 37, 48]

Option 1
str2double(strcat(string(A),string(B)))
Option 2
str2double(reshape(compose('%i%i',A(:),B(:)),size(A,1),size(A,2)))

Note that if you have negative entries then you will need to define what the results are expected to be.

Mohammad Sami Thank you , these options are great, but they don't work when the second matrix has a negative element

Thank you, but I don't want it to be one number,,, also I do have negative numbers in my actual code, this is just an example. I want them to combine so that each element will stand near the other matrix's corresponding element

What does "stand near" mean to you?

kron(A, [1 0]) + kron(B, [0 1])

I want them to be separate numbers and be close be the other corresponding one ..for example when
A(1,2)=-2
B(1,2)=-6
then C(1,2)=-2 -6

That is not possible in MATLAB unless you are willing to use cell arrays C{1,2} = [-2 -6]

okay ,sorry I didn't see your 'kron(A, [1 0]) + kron(B, [0 1])' answer , I think this is the most convenient one. Thank you !!!
