紧急求助!
需要写一篇仿真的论文,导师已经催了好几天了；我以前没有学过Matlab.程序编过之后错误太多,在论坛上发过几个帖子,可是时间来不及了,只有把程序全贴上来,请高手帮忙弄出来,这里感激不尽!angel=(0:pi/100:2*pi);
x=200*cos(angel);
y=200*sin(angel);
z=sqrt(420^2-(200*cos(angel)).^2);
plot3(x,y,z);
grid;
xlabel({'X'});
ylabel({'Y'});
zlabel({'Z'});
A=sqrt(x.^2.*z.^4+(y.*z.^2+x.^2.*y).^2+x.^4.*z.^2);
B=sqrt(x.^2.*y.^4+(x.^2.*z+y.^2.*z).^2+x.^4.*y.^2);
for i=0:size(angel)
L=[y.*z,-x.*z,-x.*y];
M=[-A.*x.*y.^2+B.x*z.^2,A.*x.^2*y.^2+B.*(y.*z.^2+x.^2*y),-A.*(x.^2.*z+y.^2.*z)-B.*x^2.*z];
N=[det(L(2),L(3);M(2),M(3)),det(L(3),L(1);M(3),M(1)),det(L(2),L(1);M(2),M(1))];
T(:,:,i)=[L(1),N(1),M(1);L(2),N(2),M(2);L(3),N(3),M(3)];
E=(0,0,150,1)*T';
rE=sqrt(E(1)^2+E(2)^2);
rD=220*sin(pi/6)+rE;
zD=220*cos(pi/6)+E(3);
l=sqrt((rD-230)^2+(zD-1000)^2);
end
θ1=atan(E(2)/E(1));
θ2=atan((1000-zD)/(rD-230))-acos((l(i)^2+325^2-300^2)/2*325*l);
θ3=pi-acos((l(i)^2-325^2-300^2)/2*325*300);
θ4=pi/2+pi/6-θ2-θ3;
θ5=atan(T(2,3,:)./T(1,3,:));
θ6=atan((-T(1,1,:).*sin(θ5.)+T(2,1,:)*cos(θ5.))/(-T(1,2,:).*sin(θ5.)+T(2,2,:).*cos(θ5.)));
θ7=atan((T(1,3,:).*cos(θ5.)+T(2,3,:).*sin(θ5.))/T(3,3,:));
plot(θ1,θ2,θ3,θ4,θ5,θ6,θ7);
就是要这七条曲线,论文也就差这个了,这里再次感谢!
