how to plot 3d using coordinates

Hi fellows, Could you tell me how to plot 3d using coodinates? For example, I have the coordinates for one point is 0.2,0.3,04 and for another point is -0.3,0.3,0.1. How can I plot them in one graph and also connect the two points?

Answer 1

[Azzi Abdelmalek]

v1=[0.2,0.3 4 ],
v2=[-0.3,0.3,0.1],
v=[v2;v1];
plot3(v(:,1),v(:,2),v(:,3),'r')

line([x1 x2],[y1 y2],[z1 z2]) and you can put as many points as you want in each vector obviously

That's how to draw a line in 3d, there are MANY other 3d plotting functions

but the image I got usng line is not 3d. It is still a 2 dimensions plot...

[Deming Zheng]

the line command works, you can simply use "view(az, el)" to see the 3d plot. where (AZ,EL) = view returns the current azimuth and elevation. e.g. try view(30,10) after the line command. clc clear x = line([0 1],[0,0],[0,0],'color','r'); y = line([0 0],[0,1],[0,0],'color','g'); z = line([0 0],[0,0],[0,1],'color','b'); view (30,30) grid on

or use

 rotate3d on

to drag the axes freely

v1=[0.2,0.3 4 ],

v2=[-0.3,0.3,0.1],

v=[v2;v1];

plot3(v(:,1),v(:,2),v(:,3),'r')
