MATLAB: Using for loop with 2 variables.

Question

a=[1;2;3;4]
b=[5;6;7]
for i=1:4 
for j=1:3
x=a(i)+b(j)
end
end

% it gives 12 x but I cannot merge all x(i) like that:

x=[6;7;8;7;8;9;8;9;10;9;10;11] %[x(1);x(2);x(3);......x(12)]

Answer 1

Sermet, use

 a = [1;2;3;4]
 b = [5;6;7]
 kk = 1;
 for ii = 1:4 
   for jj = 1:3
     x(kk) = a(ii) + b(jj)
     kk    = kk + 1;
   end
 end
