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.
