Webb20 nov. 2024 · $\begingroup$ In order to determine whether they used forward (explicit) or backwards (implicit) finite differencing, they need to apply it to an ODE. Here, I can't determine which one they used because you haven't told me what the authors applied it to and what the result was. Why don't you write out exactly what it says in the book, before …

Webb8 apr. 2024 · The differences Ax becomes the derivative d x d y = b ( t) The differences of squares 0,1,4,9 are odd number 1, 3, 5. The derivative of x ( t) = t 2 is 2 t. A perfect analogy would produce even number b = 2, 4, 6 at times of 1, 2, 3. But differences are not the same a derivatives, and our matrix A produces not 2 t but 2 t − 1: Backward difference: Webb17 juli 2015 · In addition to that we can make a relative comparison between time numerical integration ( it can be viewed like extrapolation method) and differentiation ( it can be viewed like interpolation method) as long as the "numerical integration" is stable .
