在Matlab中绘制3D点并通过线顺序连接它们

Question

I have an array that contains 3D float points. Not only I want to depict them in a figure but also I want to connect them with lines.

Example) lets say we have array called X:

X=[0, 0, 0; 0.48, -0.88, 0.09; -1.06, 0.55, 0.9; -0.65, 1.5, -1.44; 1.1, 0.59,
-1.11;0.76, 0.86, -0.52; -1.08, -0.28, 0.55; 1.47, -1.21, 0.14; 1.42, -2.15, 0.71; -0.64,  
1.87, 2.4;2.32, -2.44, 2.02; 2.25, -2.56, -3.03; 2.35, 2.65, -1.5; 0.23, -2.25, 2.78; 2.47,  
-3.12,  -1.91; 2.27, 1.37, -3.05; 2.3, 1.9, -1.29; -1.77, -0.51, 2.33];  

    X1= [0,0,0]  
    X2=[0.48, -0.88, 0.09]  
    X3=[-1.06, 0.55, 0.9] ...   

now I want that X1...Xn to be drawn in figure as points then X1 get connected to X2, X2 get connected to X3, X3 get connected to X4, etc

how could I do that?

Here is what I ve done but I get a wrong figure:

figure;hold on;  
    P=[];  
    for i=1:size(X,1)  
    x=X(i,1);  
    y=X(i,2);  
    z=X(i,3);  
    A=[ x,y,z];  
    P=vertcat(P,A);  
    plot(P);  
    end  

And Here is the output:

Answer 1

Check out the plot3 documentation .

In particular, plot3(X, Y, Z) will plot the points and join them with a line.

In your case:

plot3(X(:, 1), X(:, 2), X(:, 3))
