two cell array like

 A={1,2,3,4,5} %cell array
 B={11,12,13,14,15}   %cell array
 for i=1:length(A)
 C            %variable
 D             %variable
 end

in first iteration C take 1 from A and D take 11 from B

second iteration C take 2 from A and D take 12 from B

So on

use only single for loop

Why are these values in cell arrays anyway? Unless you have mixed data types or different sizes, just use a simple numeric array to store those values.

Also note that, depending on what operations you need to perform, the entire loop might be able to be replaced with vectorized code. If you show us what the operations are inside the loop, then we could show you if this can be simplified by vectorization.

 C = cell( size(A));
 D = cell( size(B));
 for ii=1:length(A)
     C(ii) = A(ii);
     D(ii) = B(ii);
 end

Addendum

Without the loop - vectorized

    C = A;
    D = B;

You mean like

 for cnt=1:length(A)
   C=A{cnt};
   D=B{cnt};
 end

Actually, there is no need for cell arrays here. In case this is just a simplified example and A and B will be of different kind in your final program, it's fine. Otherwise, I would make A and B just normal double arrays.
