MATLAB: Hi everyone , i need help to do this , thank u

MATLAB

clear all
clc
A=10*randn(1,8);
B=10*randn(1,8);
EA=A+2
EB=B+2
E=min(EA,EB)
% i need the value of A and B in a row vector that corrispond to the value of E
thank u

The variable 'idx' tells you whether the minimum came from EA (idx=1) or EB (idx=2). Use that to pull out values from A and B as needed.
[E, idx] = min([EA;EB]); %only works if EA and EB are same size
% If you want one row vector of A and one for B
A0 = A(idx==1);
B0 = B(idx==2);
% If you want one row vector that combines A and B
AB = nan(1, length(E));
AB(idx==1) = A(idx==1);
AB(idx==2) = B(idx==2);
