Index exceeds array dimensions. Index value 150002 exceeds valid range [1-150001] for array 'v'.

I tried to run this sentence using Simulink but this error keeps popping upfor

for n = 1:length(t); % Start simulation
    v(n+1) = v(n) + (g*sin(theta(n)) - k./m.*v(n)).*dt;
    theta(n+1) = theta(n) - 1./L.*v(n).*dt;
end

Answer 1

[VBBV]

for n = 1:length(t)-1;

Error shows clearly that vector v has 1 additional element. Change the loop as above since v(n+1) should correspond to last element in vector v. A better way is to preaalocate array as

v = zeros(1,length(t))
