example
2 3
3 4
5 3
1 2
3 2.5
the answer will be a vector (5+3, 3+4+2) the code may be incorrect but, I only try my assumptions.
v=[1400 1600 1200 800 1000];
r=[500 400];
for i=1:numel(v)
t=0;
for j=1:numel(r)
eet(i,j)=v(i)./r(j);
et(i,j)=v(i)./r(j);
c(i,j)=eet(i,j)+t;
ctc(i,j)=eet(i,j)+t;
t=t+eet(i,j);
end
end;
M=max(eet,[],2); % this gives me all the maximum value along a colunm vector

All you need is max and accumarray:
>> M = [2,3;3,4;5,3;1,2;3,2.5];
>> [V,I] = max(M,[],2);
>> B = accumarray(I,V)
B =
