Problem with UKF weights when calculating predicted state
I'm having troubles implementing a UKF during the calculation of $\overline{\mu_t}$, specifically in this step:
$$\overline{\mu_t} = \sum_{i=0}^{2n}w_m^{[i]}\chi_t^{*[i]}$$
My problem I'm facing is ...

Incremental (on-the-fly) smooth trajectory interpolation algorithm from waypoints?
short version (TL;DR):
I'm receiving x(t) waypoints "online", which I must travel through at the specified times. I need an algorithm that would plan a smooth trajectory in-between them without ...
