generating sequence number with time sampling

Hi all!

I need to update the value of a. for t=1:1000.

while there is time sampling tk which has the sequence like this [0 2 5 7 10 12 15 .... 55 57 60]

i was trying the code below. but it doesn't work. may anyone help me? thanks in advance!

for t = 1:1000
    if mod(t,2)==1
        p=2;
    else 
        p=3;
    end
    tk(1)=0;
    tk(t+1)=tk(t)+p;
    if t==tk
        a(x)=a(x)+1
    else
        a(x)=a(x)
    end
end

out = cumsum([0;rem(0:23,2)' + 2]);

for "t = 1:1000":

t = (1:1000);

tt = mod(t,2);
out = cumsum([0;2 + tt(2:end)]);
