How to plot vectors as 3D plot

So i have a platform and a base. The platform has the following points B1= (15 15 0) B2= (-15 15 0) B3= (-15 -15 0) B4= (15 -15 0) And it's moving so i put those points in an equation with respect to some angles so it becomes b1 = P + (R*B1) b2 = P + (R*B2) b3 = P + (R*B3) b4 = P + (R*B4) Where P is [0 0 20] and R is a rotation matrix with respect to some angles And the base has the corresponding points A1 = (5 14 0) A2= (-30 30 0) A3= (-30 -30 0) A4= (5 -14 0)

How do i plot bi and Ai such that the base is connected with the platform with a line between the point in the platform with the corresponding one in the base ?

Are you expecting something like this?

clc; clear all ;
% Platform
B = [15 15 0 ;
    -15 15 0 ;
    -15 -15 0 ;
    15 -15 0] ;

P = [0 0 20] ;
P = repmat(P,[4,1]) ;
% A random rotation 
R = rand(1,3) ;
R = repmat(R,[4,1]) ;
%
b1 = P + (R.*B) ;

% Base
A = [5 14 0 ;
    -30 30 0 ;
    -30 -30 0 ;
    5 -14 0] ;

my_vertices = [A ; b1] ;
my_faces = [1 2 3 4; 2 6 7 3; 4 3 7 8; 1 5 8 4; 1 2 6 5; 5 6 7 8];
patch('Vertices', my_vertices, 'Faces', my_faces, 'FaceColor', 'w');

What does repmat mean? R is not a random variable, it's a 3x3 matrix with a specific formula that I haven't mentioned here

Yeah..I thought so...It can be modified...for R as 3x3
