deviation from the average value less
显示 更早的评论
hello everyone, I have a vector composed of 34 rows by 40 columns, I would like to calculate the average value of each row (therefore a 34x1) and then find the column of the starting vector that is closest to that column made up of average values, to then be able to find the corresponding column number . how can do it? thanks
my array name is veT:
for i = 1: duration
traci.simulation.step();
if i==1
for f=1:length(semafori)
traci.trafficlights.setPhaseDuration(semafori{f}, nominali(f,1))
end
end
for n=1:length(induction)
vec_sec(n,i)=traci.inductionloop.getLastStepVehicleNumber(induction{n});
end
for v=1:length(k)
if i==t(v)
for j=1:length(vec_sec(:,1))
veT(j,v)=sum(vec_sec(j,(t(v)-(T-1)):t(v))); % this is vector by34x40
end
for f=1:length(semafori)
traci.trafficlights.setPhase(semafori{f},0);
traci.trafficlights.setPhaseDuration(semafori{f},nominali(f));
end
end
end
end
traci.close

[m,i] = min(vecnorm(veT-mean(veT,2)))

I don't know where to place the command.
Your question was that you have a (34x40) matrix, so you should place the command in your code after the matrix is formed - so most probably out of all at the end. And yes, the "i" refers to the column which is most similar to the average column (if you measure "similarity" by the 2-norm of the difference of the columns with the average column).

This is the minimum value itself, i.e. the minimum 2-norm of the difference between the columns and the average column.
