%求三个圆所相交部分的三个交点坐标所成三角形的重心坐标(barycenter_x,barycenter_y)
%三个圆(圆心为x1,y1半径为r1。圆心为x2,y2半径为r2。圆心为x3,y3半径为r3)
function [barycenter_x,barycenter_y]=barycenter(x1,y1,r1,x2,y2,r2,x3,y3,r3)
    [fn1x,fn1y,fn2x,fn2y,fn3x,fn3y]=c3point(x1,y1,r1,x2,y2,r2,x3,y3,r3);
    barycenter_x=(fn1x+fn2x+fn3x)/3;
    barycenter_y=(fn1y+fn2y+fn3y)/3;
