% A >>>>> MA >>>>>> min E >>>> from this i need the corrispondat column vector of A
% B>>>>>> MB >>>> min E >>>>> from this i need the corrispondat column vector of B
% so at the end i need a matrix 2x8 that contain only the the mix of A and B hat corrispond to the minimum value of MA and MB
A=10*randn(2,8); % from this matrix in need only the column vector that corrispond to the min value of MA
B=10*randn(2,8); %from this matrix in need only the column vector that corrispond to the min value of MB
MA=mean(A,1)
MB=mean(B,1)
E=min(MA,MB)

[~, idx] = min( MA );
resA = A(:,idx); ### Star Strider (view profile)

If you want to find the column of ‘A’ or ‘B’ that has the minimum value in their respective matrices, this works:
[~,cA] = find(A == min(A(:)));
[~,cB] = find(B == min(B(:)));
Here, ‘cA’ is the column of ‘A’ that has the minimum, the same applies to ‘cB’ and ‘B’.
