create_bricks.m

this a 3d fdtd code using matlab and it can be used as a reference for other structures. Dear sir,

disp('creating bricks');

for ind = 1:number_of_bricks
    % convert brick end coordinates to node indices 
    blx = round((bricks(ind).min_x - fdtd_domain.min_x)/dx) + 1; 
    bly = round((bricks(ind).min_y - fdtd_domain.min_y)/dy) + 1; 
    blz = round((bricks(ind).min_z - fdtd_domain.min_z)/dz) + 1; 

    bux = round((bricks(ind).max_x - fdtd_domain.min_x)/dx)+1; 
    buy = round((bricks(ind).max_y - fdtd_domain.min_y)/dy)+1; 
    buz = round((bricks(ind).max_z - fdtd_domain.min_z)/dz)+1; 

    % assign material type of the brick to the cells
    material_3d_space (blx:bux-1, bly:buy-1, blz:buz-1) ...
        = bricks(ind).material_type;
end
