Please edit your question and post your code as text formatted with the CODE button. We cannot copy & paste pictures into MATLAB to try out your code. My guess is that u is a variable and not a function, so using t(i) in the indexing may be the cause of the problem.

Yes. I think you are correct. The obvious problem is if u is a variable, are the terms like (u(t(i) + pi)). t(i) + pi will never be an exact integer.

Pre allocating arrays may not solve your problem, as the error msg states you are indexing array ”u” using either negative integers or fractions, check if “t(i)-3” value turns out to be a negative or fraction.
