Growbubbles获取质心点并返回不重叠的最大半径圆或球体
Growbubbles - maximum radius packing
%GROWBUBBLES packs maximum radius circles at given central locations
%
% PTRADS = GROWBUBBLES(PTS) returns the radius of circles at coordinates in PTS with all radii
% maximised but without any circles overlapping. PTS is a P-by-N matrix of P "N-dimensional"
% points.
%
% If no output argument is given, PTSIN will be plotted as circles (2D) or spheres (3D) to the
% current figure.
%
% Example:
%
% % Find the maximum packed radius of 20 random points
% x = rand(20, 2);
% ptRads = growbubbles(x);
