update values in a for loop except one

hi everyone, i have the following problem. I have a simulation seconds ranging from 0 to 630 seconds, at which every 90 I would like to perform actions.
now here I would like to obtain a newgreentime that every in every value of t (v) updates according to a function of this type, in practice that takes into consideration one column at a time of the veicoliTT (n, v) to be subtracted from the greentime calculated in the t(v) previous. as soon as I got this value I would like to use it to set it to yet another function. This whole operation should be computed for every v, except for greentime with v = 1, for which I would like to take a constant value outside the for loop instead with the values 45,45,45,45 (while the veicoliTT (n, v) for v = 1 must be equally calculated by the for loop). how can i do this?
L is constant matrix 4x34
Thank you so much
SIM_STEPS = [1 630];
beginTime = SIM_STEPS(1);
duration = SIM_STEPS(2);
endTime = SIM_STEPS(1) + SIM_STEPS(2) - 1;
k=1:floor(endTime/T); %is a vector ranging from 1 to 7
t = T:T:duration; % returns the values 90,180 ... 630
inductionID=traci.inductionloop.getIDList(); % function that creates me a vector of 34 values
T=90;
greentime=[45 45 45 45]'; %I would like it to be the value of newgreentime for v = 1
for i = 1:duration
traci.simulation.step();
for n = 1: length(inductionID)
num(n,i)=traci.inductionloop.getLastStepVehicleNumber(inductionID{n});
% creates a 34x630 vector
end
for v=1:length(k)
if i==t(v)
for n = 1: length(inductionID)
veicoliTT(n,v)=sum(num(n,(t(v)-(T-1)):t(v)));% I create a sum vector of 90 elements for each value of v
newgreentime(v)=newgreentime(v-1)-L*veicoliTT(:,v); % don't work
end
end
end
end

Not understanding what you are trying to do exactly. But one way to test that a counter has reached some multiple of an integer T is to use the modulus function:
if mod(i, T) == 0
for n = 1: length(inductionID)
veicoliTT(n,v)=sum(num(n,(t(v)-(T-1)):t(v)));% I create a sum vector of 90 elements for each value of v
newgreentime(v)=greentime(v)-L*veicoliTT(:,v); % don't work
end
end

If you really want seconds... you might want to use clock and etime. I don't entirely understand what you want. For example something like this:
stime=clock;
itime=stime;
v=0;
count=1;
while etime(stime,clock)*1000<630
traci.simulation.step();
for n = 1: length(inductionID)
num(n,count)=traci.inductionloop.getLastStepVehicleNumber(inductionID{n});
% creates a 34x630 vector
end
count=count+1;
if etime(itime,clock)*1000>90
itime=clock;
v=v+1;
for n = 1: length(inductionID)
veicoliTT(n,v)=sum(num(n,(t(v)-(T-1)):t(v)));% I create a sum vector of 90 elements for each value of v
newgreentime(v)=greentime(v)-L*veicoliTT(:,v); % don't work
end
end
end
