Given a set of 2D points, I'd like to create a power diagram that is cropped into a rectangle.
There is this:
https://au.mathworks.com/matlabcentral/fileexchange/44385-power-diagrams
but it's written with loops (slow), and it doesn't crop but based on the convex hull.
I was hoping for something more robust such as
https://au.mathworks.com/help/matlab/math/voronoi-diagrams.html
Otherwise, I'll need to use cgal

In case this hasn't been resolved, here's a faster version of the same function: https://www.mathworks.com/matlabcentral/fileexchange/56633-fast-bounded-power-diagram

Might do the trick, thanks. However, I found out that there's a differnt approach (using Sinkhorn67), which I need to look into.
