matlab解高次四个未知数方程组
r^2= (x-1647)^2+(y-2728)^2+(z-14.08)^2
r^2= (x-6869)^.2+(y-7286)^2+(z-16.58)^2
r^2= (x-4748)^2+(y-7293)^2+(z-18.38)^2
r^2= (x-4742)^2+(y-7293)^2+(z-21.87)^2
优质解答
syms r x y z;
solve('r^2-(x-1647)^2+(y-2728)^2+(z-14.08)^2','r^2-(x-6869)^.2+(y-7286)^2+(z-16.58)^2',...
...'r^2-(x-4748)^2+(y-7293)^2+(z-18.38)^2','r^2-(x-4742)^2+(y-7293)^2+(z-21.87)^2',r,x,y,z)
%解不出来啊
