I want to store the values of count1 in the vector of zeros I have defined before the for loop. So the vector should be like [0 0.01 0.02 0.03 ..]. However, after the first iteration I get an error saying index exceeds the number of array element (1)

    count=0.0
    dt=0.01
    count1=zeros(1,300);
    count1=zeros(1,300);
    for n = 1:300
        count1(n)=count(n)+dt(n);   
    end

What is count1 and count? Why do you intialize count1 twice but not count? Do you even need count at all?

Using linspace or colon would be much simpler and more efficient. And of course linspace avoids nasty floating point error accumulation.

The error refers to both ‘count’ and ‘dt’, that each have only one element, so you cannot subscript them beyond 1.

Try this:

count=0.0
dt=0.01
count1=zeros(1,300);
for n = 1:300
    count1(n)=count+dt;
end

Do you want to try it vectorized?

dt = 0.1
count1 = [0, cumsum(dt*ones(1,299))]
