Concatenate arrays horizontally n matrix by loop

Please for a n matrix (with a same nbr of rows and columns), i want to Concatenate them horizontally by a loop,

A1 = [1 2 3; 2 4 6];
A2 = [4 5 6; 8 10 12];
A3 = [7 8 9; 14 16 18];
A4 = [10 11 12; 20 22 24];

AT = horzcat(A1,A2, A3, A4)

For n matrix i think to create a zero matrix and fill it by a loop

n=4  
[mA1,nA1] = size(A1)
ATotal = zeros(mA1,nA1*n)

Please any help

A(:,:,1) = [1 2 3; 2 4 6];
A(:,:,2) = [4 5 6; 8 10 12];
A(:,:,3) = [7 8 9; 14 16 18];
A(:,:,4) = [10 11 12; 20 22 24];

B = []; 
for i=1:size(A,3)
  B = [B, A(:,:,i)];
end
