How to generate random points in a 3d line, if two end points are known??

Hello MATLAB Community,

I am working on a project and I am having a small problem, where I have to generate random points between two known points in 3D space.

for example : point A = [ 0, 0, 405] and point B = [ 4.5, -5.5, 480], I need to generate say 50 - 100 random points in-between point A & B.

Can anyone please help me with any suggestions.

Thank you in advance!!

I really appreciate your help.

Kind regards,

Shiv

A = [ 0, 0, 405] ; 
B = [ 4.5, -5.5, 480] ; 

AB = B-A ;   % vector 
t = sort(rand(1,100)) ;  % random points  
% Parametric equation of line in 3D 
P = A'+t.*AB' ;
% plot 
figure
hold on
plot3(A(1),A(2),A(3),'*r')
plot3(B(1),B(2),B(3),'*r')
plot3(P(1,:),P(2,:),P(3,:),'.-b')
