Everywhere in between, use the central difference formula. This allows you to compute a derivative at every point in your vector, and will provide better results than using recursive applications of "diff".

Webforward difference at the left endpoint x = x 1, a backward difference at the right endpoint x = x n, and centered difference formulas for the interior points. WebForward Difference Approximation. Throughout numerical weather prediction, you often need to calculate the gradient of a function at a number of points. As we rarely know the equation which defines the function, we need to calculate numerically an estimate of the gradient. This method requires the use of finite difference schemes. In this ...
WebA forward difference, denoted of a function f is a function defined as Depending on the application, the spacing h may be variable or constant. When omitted, h is taken to be 1; that is, A backward difference uses the function values at x and x − h, instead of the values at x + h and x : Finally, the central difference is given by WebUse forward difference approximation of. the first derivative of. ν (t) to calculate the acceleration at = t s 16 .
