WebDec 7, 2024 · cumtrapz (), cumsum () and similar do what they state they do: summing the input array cumulatively. If the summed array starts with 0 as with your input array ( dydx ), the first element at the summed array is also zero. To fix it in your code, you should add the offset to the cumulated sum: dydx_int = dydx_int + y [0]
