有大佬吗？想要求解六​元二次方程组，但是总​是有问题啊 。

有个问题，怎么把代码编写到帖子里啊

function sol= myfun(P1,P2,P3)

syms x xb xc y yb yc eq1 eq2 eq3 eq4 eq5 eq6 real

eq1=x^2+y^2-P1^2;

eq2=(xb-5)^2+yb^2-P2^2;

eq3=xc^2+(yc-6)^2-P3^2;

eq4=(xc-xb)^2+(yc-yb)^2-3^2;

eq5=(x-xc)^2+(y-yc)^2-(3*2^(1/2))^2;

eq6=(x-xb)^2+(y-yb)^2-3^2;

sol=vpasolve(eq1,eq2,eq3,eq4,eq5,eq6);

end

function sol= myfun(P1,P2,P3)
syms x xb xc y yb yc real
eq1 = x^2+y^2-P1^2 == 0;
eq2 = (xb-5)^2+yb^2-P2^2 == 0;
eq3 = xc^2+(yc-6)^2-P3^2 == 0;
eq4 = (xc-xb)^2+(yc-yb)^2-3^2 == 0;
eq5 = (x-xc)^2+(y-yc)^2-(3*2^(1/2))^2 == 0;
eq6 = (x-xb)^2+(y-yb)^2-3^2 == 0;
sol = vpasolve([eq1,eq2,eq3,eq4,eq5,eq6],[x xb xc y yb yc]);
end

clear; clc; close all; 
P1 = 5; P2 = 5; P3 = 3;
sol = myfun(P1,P2,P3);
disp( [sol.x sol.xb sol.xc sol.y sol.yb sol.yc] )
