Hi,
I understand that you want to achieve full coverage of an irregular region using Voronoi diagrams.
A possible approach would be to first define the irregular region as a polygon using "polyshape". Then generate a set of points inside that region which will act as Voronoi seed points. After generating the Voronoi diagram using "voronoin", you’ll need to clip each Voronoi cell to the irregular boundary using "intersect" with the polygon. Hence, this way, each sub-region is confined to the area of interest while still preserving the spatial structure of a Voronoi tessellation.
To know more about the above mentioned functions, refer to the following MathWorks documentation links::
