我的循环到第二次就不能运行了,请问是哪里出了问题呢?
for a=1:3
d4(a)=200*(rand(1)*0.1+0.1);
l4(a)=200*(rand(1)*0.3+0.1);
l2(a)=200-d4(a)-l4(a);
n=1000;
for i=1:1000
theta1(i)=60*rand(1)-30;
theta2(i)=90*rand(1)-60;
theta4(i)=0;
theta3(i)=60*rand(1);
x(i)=l4(a)*cosd(theta1(i))*sind(theta2(i)+theta3(i))*cosd(theta4(i))-l4(a)*sind(theta1(i))*sind(theta4(i))+cosd(theta1(i))*cosd(theta2(i)+theta3(i))*d4(a)+l2(a)*cosd(theta1(i)+cosd(theta2(i)));
y(i)=l4(a)*sind(theta1(i))*sind(theta2(i)+theta3(i))*cosd(theta4(i))+l4*cosd(theta1(i))*sind(theta4(i))+d4(a)*sind(theta1(i))*cosd(theta2(i)+theta3(i))+l2(a)*sind(theta1(i)+cosd(theta2(i)));
z(i)=-l4(a)*cosd(theta2(i)+theta3(i))*cosd(theta4(i))+sind(theta2(i)+theta3(i))*d4(a)+l2(a)*sind(theta2(i));
end

end
plot3(d4(a),l4(a),count(a),'r*')
end
