briefly explain why you cannot compute the forward difference at the last point in a dataset. in matlab

In MATLAB, the forward difference is calculated by subtracting the value at the current point from the value at the next point in a dataset. However, it is not possible to compute the forward difference at the last point in a dataset because there is no next point to calculate the difference with. This would result in an undefined value or an error. To avoid this issue, it is necessary to ensure that the dataset being processed has enough points to calculate the forward difference.
