How can I store the result after each iteration in a row vector?

Below is the sum equation which is of similar form that I need to write in my Objective Function.

I have written the following code using two 'for' loops, it's working fine but the final answer Asum(As) it is storing is only of the last iteration.

Ad = [1 2];
Ac = [1 2 3 4];
for i=1:lenght(Ac)
    for j=1:length(Ad)    
      As=Ad(j)+Ac(i)
    end
end

whereas I need the result in the form of a row vector as shown below:

As = [2 3 3 4 4 5 5 6]

Kindly help, thanks

Using two loops is not a very good use of MATLAB.

  Ad = [1,2];
  Ac = [1,2,3,4];
  C = reshape(Ac+Ad(:),1,[])

C = 1×8

2 3 3 4 4 5 5 6

Thank you Stephen, I'll modify my code.

A quick hack would be:

Ad = [1 2];
Ac = [1 2 3 4];
As=[];
for i=1:length(Ac)
    for j=1:length(Ad)    
      As=[As Ad(j)+Ac(i)]
    end
end

Thanks David, I get it.. ^^
