Hi, I have the following two square matrices:
A=
17 24 1
23 65 7
4 6 13
B=
18 27 35
2 5 8
4 16 11
I want to concatenate the elements of matrices A and B to form a cell C such that:
C= <17,18> <24,27> <1,35>
<23,2> <65,5> <7,8>
<4,4> <6,16> <13,11>
Please help. (I want to avoid using for loop)

n=numel(A)
out=arrayfun(@(x) [A(x) B(x)],1:n,'un',0)

Ok, what about
out=arrayfun(@(x,y) num2str([x y]),A,B,'un',0)

Like this?
C = arrayfun(@(x) ['<' num2str(A(x)) ',' num2str(B(x)) '>'], 1:numel(A), 'un', 0);
C = reshape(C, [3 3]);

cellfun(@squeeze,num2cell(cat(3,A,B),3),'Uni',false)

This is what I wanted.
A=magic(3);
B=magic(3);
C = arrayfun(@(x) [num2str(A(x)) ' ' num2str(B(x))],1:numel(A), 'un', 0);
Z=reshape(C,3,3)
Thanks for your help! Azzi, Thorsten, Sean. :-)
