If your u(t) is a symbolic equation, use quad()

If your u(t) is numeric data, use cumsum()

[Walter Roberson]

Would you not use int() for symbolic equations ?

[Fangjun Jiang]

You are probably right. It looks like there are three int() functions, Symbolic integration, States from CIC filter, and Smallest built-in integer fitting stored integer value of fi object. I have none of them.
