for i = 1:duration
traci.simulation.step();
for n = 1: length(inductionID)
veicoliOGNIISTANTEsuInduction(n,i)=traci.inductionloop.getLastStepVehicleNumber(inductionID{n});
end
for v=1:length(k)
if i==t(v)
for n = 1: length(inductionID)
veicoliT(n,v)=sum(veicoliOGNIISTANTEsuInduction(n,(t(v)-(T-1)):t(v)));
end
newgreentime(:,v)=L*veicoliT(:,v); % L is a constant matrix
end
end
hi all, i have a vector n rows by v (whose columns are indexed). my vector newgreentime (:, v) in the considered v becomes a vector 4 x1, I would like to use this vector in a 3 dimensional vector 2x2xv how can I do it?

newgreentime(:,:,v) = reshape(L*veicoliT(:,v), 2, 2); % L is a constant matrix
This assumes that you want the order
A B C D ->
[A C
B D]
if you need
[A B
C D]
then
newgreentime(:,:,v) = reshape(L*veicoliT(:,v), 2, 2).'; % L is a constant matrix

" .' " (dot single-quote) is transpose.
" ' " (single-quote) is complex conjugate transpose.
If the thing you are transposing (say X) contains only real values (i.e., no complex numbers), then X.' is the same as X'
