Creating Randomly Placed Cubes

I am trying to create an app through app builder in which I can use assigned values within input fields to randomly generate cubes (lysosomes) inside of my defined rectangular channel with a specific material so that I can continue to run simulations. I want to click a button that is attached to a method to perform this action. I have MatLab code that creates the particles how I wanted to but I am unsure how to convert the code so that it would work in the method. I have all of my parameters linked to an input field within the app builder form as well. If using LiveLink would make more sense to do I would appreciate getting help on how to do that as well.
Here is the working MatLab code:
% Rectangular Prism Placement in Rectangular Area Without Overlap Script
% Clear workspace and command window clc; clear;
% Prompt user for dimensions of the channel length_mm = input('Enter the length of the channel (in mm): '); width_mm = input('Enter the width of the channel (in mm): '); height_mm = input('Enter the height of the channel (in mm): ');
% Prompt user for dimensions of the lysosomes rect_length_um = input('Enter the length of the lysosome (in micrometers): '); rect_width_um = input('Enter the width of the lysosome (in micrometers): '); rect_height_um = input('Enter the height of the lysosome (in micrometers): ');
% Convert dimensions to micrometers for calculations length_mm_um = length_mm * 1000; % mm to um width_mm_um = width_mm * 1000; % mm to um height_mm_um = height_mm * 1000; % mm to um
% Prompt user for the number of prisms num_lysosomes = input('Enter the number of lysosomes to place: ');
% Validate input if length_mm_um <= 0 || width_mm_um <= 0 || height_mm_um <= 0 || num_lysosomes <= 0 || ... rect_length_um <= 0 || rect_width_um <= 0 || rect_height_um <= 0 disp('All dimensions must be positive numbers and the number of lysosomes must be a positive integer.'); else % Initialize arrays for lysosome positions lysosome_positions = zeros(num_lysosomes, 3); % Columns for x, y, z positions placed_lysosomes = 0; % Counter for placed prisms
while placed_lysosomes < num_lysosomes
% Generate a random position for a new rectangle
x = rand() * (length_mm_um - rect_length_um);
y = rand() * (width_mm_um - rect_width_um);
z = rand() * (height_mm_um - rect_height_um); % Random height placement
% Check for overlap with existing rectangles
overlap = false;
for j = 1:placed_lysosomes
if (x < lysosome_positions(j, 1) + rect_length_um && ...
x + rect_length_um > lysosome_positions(j, 1) && ...
y < lysosome_positions(j, 2) + rect_width_um && ...
y + rect_width_um > lysosome_positions(j, 2) && ...
z < lysosome_positions(j, 3) + rect_height_um && ...
z + rect_height_um > lysosome_positions(j, 3))
overlap = true;
break;
end
end
% If no overlap, place the rectangle
if ~overlap
placed_lysosomes = placed_lysosomes + 1;
lysosome_positions(placed_lysosomes, :) = [x, y, z];
end
end
% Plot the rectangles in 3D
figure;
hold on;
for i = 1:placed_lysosomes
% Define the corners of the rectangle in mm
x = lysosome_positions(i, 1) / 1000; % Convert from um to mm
y = lysosome_positions(i, 2) / 1000; % Convert from um to mm
z = lysosome_positions(i, 3) / 1000; % Convert from um to mm
% Create a rectangular prism using patch
% Correctly define vertices for the lysosomes
l = rect_length_um / 1000; % Convert length to mm
w = rect_width_um / 1000; % Convert width to mm
h = rect_height_um / 1000; % Convert height to mm
vertices = [0 0 0; l 0 0; l w 0; 0 w 0; ...
0 0 h; l 0 h; l w h; 0 w h]; % Define vertices
faces = [1 2 3 4; 5 6 7 8; 1 2 6 5; 2 3 7 6; ...
3 4 8 7; 4 1 5 8];
% Transform the lysosome to its position
for j = 1:size(faces, 1)
patch('Vertices', vertices + [x, y, z], ...
'Faces', faces, ...
'FaceColor', rand(1, 3), ...
'FaceAlpha', 0.5);
end
end
% Set plot limits
xlim([0, length_mm]); % Limits in mm
ylim([0, width_mm]); % Limits in mm
zlim([0, height_mm]); % Limits in mm
% Set equal scaling for all axes
daspect([1 1 1]);
% Labels and title
xlabel('X (mm)');
ylabel('Y (mm)');
zlabel('Z (mm)');
title('Random Placement of Lysosomes');
grid on;
view(3);
hold off;
end
I also have attached pictures of what the form in my app look like. Any help on this would be greatly appreciated.
