In practice, Voronoi computation is not practical in dimensions beyond 6-D for moderate to large data sets, due to the exponential growth in required memory. If Matlab doesn't have this, you could manually calculate the intersection between the voronoi lines and the boundary lines of your polygon, and then calculate a new polygon based on that, from which you then calculate the area. This is part of my PhD research project. For each input point, the surrounding region contains all points on the plane that are closest to it compared to the other input points. 2k次。本文围绕Matlab展开，介绍了其在智能优化算法、机器学习、图像处理等多领域的应用。同时重点阐述了任意多面体有界Voronoi图，它将三维空间划分区域，在计算机图形学等领域应用广泛，但构建和计算复杂，研究人员正不断改进其算法。 Hi guys the program voronoiDiagram gives the vertices of a voronoi decomposition of a set of scattered datapoints.

MATLAB ® provides functions to plot the Voronoi diagram in 2-D and to compute the topology of the Voronoi diagram in N-D. The routine performs a Voronoi decomposition of an input dataset and constrains the vertices to the domain of the data themselves, such that even unbounded Voronoi cells become useful polygons (See attached figure).
