Accepted answer

You can use rand()

Z = rand(10,10,10);

The above gives you the unit cube. You can translate this and scale the side length:

Z = 2+(4-2)*rand(10,10,10);

Hi Wayne, I would understand

Z= rand(n,n,3);

which could be plotted using

plot3(Z(:,:,1),Z(:,:,2),Z(:,:,3),'k.')

Each point would then have 3 random coordinates. How would Z = rand(10,10,10) work and how would the coordinates be assigned?

npx=12; % no. of NPs on x-axis npy=12; % no. of NPs on y-axis npz=12;

dx=1; % distance b/w two NPs on x-axis dy=1; % distance b/w two NPs on y-axis dz=1;

x(1)=dx; % first particle is at dx from y-axis y(1)=dy; % first particle is at dx from x-axis z(1)=dz; np=0; x=zeros(1,npx); for k=1:npx x(k)=k*dx; y=zeros(1,npy); for l=1:npy y(l)=l*dy; z=zeros(1,npz); for m=1:npz z(m)=m*dz; end

end end np=npx*npy*npz sir how to plot cube by using this assembly please give me answer as earlier as you can please.will be waiting
