用Matlab画运动轨迹的程序

用Matlab画运动轨迹的程序

1、完整过程
t=0:0.01:3;
x=0.14*sin(0.5*pi*t);
y=-0.14*cos(0.5*pi*t);
z=0*t;
plot3(x,y,z),xlabel('x轴'),ylabel('y轴'),zlabel('z轴');
hold on;
t=0:0.01:1;
x1=-0.1555*t;
y1=-0.1555*t+4.9*t.^2;
z1=0.5*t.^2;
plot3(x1,y1,z1),xlabel('x1轴'),ylabel('y1轴'),zlabel('z1轴');
hold off;
2、护种过程
t=0:0.01:3;
x=0.14*sin(0.5*pi*t);
y=-0.14*cos(0.5*pi*t);
z=0*t;
plot3(x,y,z),xlabel('x轴'),ylabel('y轴'),zlabel('z轴')
3、投种过程
t=0:0.01:1;
x=-0.1555*t;
y=-0.1555*t+4.9*t.^2;
z=0.5*t.^2;
plot3(x,y,z),xlabel('x轴'),ylabel('y轴'),zlabel('z轴');
4、坐标均匀
t=0:0.01:3;
x1=0.14*sin(0.5*pi*t);
y1=-0.14*cos(0.5*pi*t);
z1=0*t;
plot3(x1,y1,z1),xlabel('x1轴'),ylabel('y1轴'),zlabel('z1轴');
hold on;
t=0:0.01:1;
x=-0.1555*t;
y=-0.1555*t+4.9*t.^2;
z=0.5*t.^2;
plot3(x,y,z),xlabel('x轴'),ylabel('y轴'),zlabel('z轴');
hold off;
axis equal;
