Dear All,
I have a matrix, like the one s below:
A=[1 2 4 8 16 32];
I want to collect all the possible cases of chossing two array from the above matrix and then have the sum of these values. like below:
1+2=3;
8+32=40;
2+16=18;
How is it possible to access all the possibe combination of two array from a matrix?

Something like this:
A = [1 2 4 8 16 32];
k = 2;
B = nchoosek(A,k)
C = sum(B,2)
Be aware how fast the size of B will increase as the length of A increases. For A of length N, B will have N!/(k!*(N-k)!) rows.
