MATLAB: Have any command for copy variable without loop.

Question

A=[1; 2; 3];
B=[4, 5, 6];
for k = 1:20
    c(:,:,k)  = A;
    d(:,:,k) = B;
end

I want to calculate values of c(:,:,k) and d(:,:,k) without loop.

Ranjan - try using repmat to repeat the copies of your arrays. Your above code should then reduce to

 C = repmat(A,1,1,20);
 D = repmat(B,1,1,20);
