how to get refractory period in neuron of long vector 1*1500000 as [0 1]?

function [stim_order,elements,v]= myfunction()
x=randn(1,5000);%plot(x);
cut_off_freq=125; 
SR=5000; %sampling rate
[A,B]=butter(4,cut_off_freq/(SR/2),'low');
filtered_signal=filtfilt(A,B,x);
rest(1:5000)=0;
x1=[rest,(filtered_signal*4)];
x2=[rest,(filtered_signal*6)];
x3=[rest,(filtered_signal*8)];
elements = {x1,x2,x3};
for i = 1:50;
%random_order(:,i)=elements(randperm(length(elements)));
random_order=randperm(length(elements));
%stim_order(:,i)=randperm(length(elements));
stim_order(i,:)=elements(random_order);
order(i,:)=random_order;
end
z=order(:)';%:-cell columns
y=cell2mat(stim_order');
v=reshape(y',1,numel(y));%v-stimulation parameter
%v=double(v);
plot(v);
a=1;%represents the saturation value
b=-2.5;%b-offset of the curve
c=0.35;%c-slope,
t=-(v+b)/c; %v-stimulation parameter
prob=a./(1+exp(t));%probability of response
plot(v,prob,'.');
xlabel('stimulation');ylabel('response');
ranvector=rand(1,1500000);
response_noresponse=(prob>ranvector);
plot(response_noresponse)

for example long vector contains [0 0 0 1 1 1 0 0 1 0 1 0 1 1] I want every after fifth element has to be consider even if its 0 or 1

please help me

What is your precise question?

[arunkumar Mohanraj]

refractory period- neuron never fire continuously. but in my long vector I'm getting sometimes continuous response of the neuron. so I want every fifth elements should be consider. because neurons never been in saturation level for long million seconds.

v=[0 0 0 1 1 1 0 0 1 0 1 0 1 1]
idx=v(5:5:end)

thank you for your effort, but I am not looking just to extract the value. my vector length is shrinks with your idea. I following idea is works. i want to learn different idea rather than true or false statement

i=1;
position=[];
while i <= length(true_false)
if true_false(i)==1
positions=[positions i];
i=i+5;
else
i=i+1;
end
end
