How can I plot the defined objects in Matlab?

Dear friends
I'm trying to execute the FDTD code of this book:
"The Finite Difference Time Domain Method for Electromagnetics With MATLAB Simulations"
In the chapter 3 I want to the see the objects defined by the define_geometry.m and show something like the following Figure.

Fig1.JPG

Code:
disp('defining the problem geometry');

bricks  = [];
spheres = [];

% define a brick with material type 4
bricks(1).min_x = 0;
bricks(1).min_y = 0;
bricks(1).min_z = 0;
bricks(1).max_x = 24e-3;
bricks(1).max_y = 20e-3;
bricks(1).max_z = 11e-3;
bricks(1).material_type = 4; 

% define a brick with material type 2 
bricks(2).min_x = -20e-3;
bricks(2).min_y = -20e-3;
bricks(2).min_z = -11e-3;
bricks(2).max_x = 0;
bricks(2).max_y = 0;
bricks(2).max_z = 0;
bricks(2).material_type = 2; 

% define a sphere with material type 5 
spheres(1).radius   = 20e-3;
spheres(1).center_x = 0;
spheres(1).center_y = 0;
spheres(1).center_z = 40e-3;
spheres(1).material_type = 5; 

% define a sphere with material type 1 
spheres(2).radius   = 15e-3;
spheres(2).center_x = 0;
spheres(2).center_y = 0;
spheres(2).center_z = 40e-3;
spheres(2).material_type = 1;
but I really can't do it?!:cry:
I attached the whole files of the chapter 3 can anybody help me, please?
Regards.

Hi friend;
when you run "fdtd_solve.m" you don't have the necessary figures. Then go to "display_problem_space.m" line 4 and make
Code:
show_problem_space = true
Then run again the "fdtd_solve.m". You will see the necessary figure.
Check the code "display_problem_space.m" from line 64 to 109 and "display_3D_geometry.m" from line 114.
Those can help to understand how to display those figures.

Hope helps
Good luck
 
u need all files of all chapters because all are linked together...then only it will work bro...
