Hi, here i have an array with random values, i have sort them and divide them in maximum and minimum values, after sorting the array the index of values is changes, if i want to add the minvalues in the orignal unsorted array with proper indexing. how should i do it?
ME=4;
E=rand(1,ME)
ES=sort(E,'descend')
Ls=length(ES);
Hl=(Ls/2);
maxval=ES(1:Hl);
minval=ES(Hl+1:end);

E(4)+minval(1) and
E(1)+minval(2)

ME=4;
E=rand(1,ME);
[ES,ii]=sort(E,'descend');
Ls=length(ES);
Hl=(Ls/2);
maxval=ES(1:Hl);
mxii = ii(1:Hl);
minval=ES(Hl+1:end);
mnii = ii(Hl+1:end);
Enew = E;
Enew(mnii) = Enew(mnii) + minval

mnii = ii(Hl+1:end);
Enow = sortrows([maxval(:),mxii(:);minval(:),mnii(:)],2);
Enow = Enow(:,1);

Sir, i want to add minval in the E array with same index values
e.g. if in the minval i have index 3,1 so i want to add them in the E array in their corresponding positions
