I have to create a cuboid at the x,y,z origin. This cuboid will undergo transformation (another 4x4 matrix of rotation and translation). I have done this so far, but cannot figure out how to plot the 8 matrices and form a cuboid from it.

x=input('enter width (x direction)= ');

y=input('enter height (y direction)= ');

z=input('enter depth (z direction)= ');

vertex1= [0 0 0 0; 0 0 0 0; 0 0 0 0; 0 0 0 1];

vertex2= [0 0 0 x; 0 0 0 0; 0 0 0 0; 0 0 0 1];

vertex3= [0 0 0 x; 0 0 0 y; 0 0 0 0; 0 0 0 1];

vertex4= [0 0 0 0; 0 0 0 y; 0 0 0 0; 0 0 0 1];

vertex11= [0 0 0 0; 0 0 0 0; 0 0 0 z; 0 0 0 1];

vertex22= [0 0 0 x; 0 0 0 0; 0 0 0 z; 0 0 0 1];

vertex33= [0 0 0 x; 0 0 0 y; 0 0 0 z; 0 0 0 1];

vertex44= [0 0 0 0; 0 0 0 y; 0 0 0 z; 0 0 0 1];

I saw this, but it wasnt very helpful as I didn't understand the code. Also, that code is for automatic rotation of the cube whereas mine would be a manual one which will undergo both translation and rotation. Do you know how to plot the 8 vertex matrices so as to form a cube/cuboid?
