I am working on "Spiral Galaxy Formation Simulation" example in Mathworks. How can I add different colors for each galaxy's bodies? There is an option in each galaxy function for color but it doesn't work.

Try this:
% Initialization/clean up
clc; % Clear the command window.
close all; % Close all figures (except those of imtool.)
clear; % Erase all existing variables. Or clearvars if you want.
workspace; % Make sure the workspace panel is showing.
format short g;format compact;fontSize = 13;numPoints = 100;points_x = rand(1,numPoints) - 0.5;points_y = rand(1,numPoints) - 0.5;points_z = rand(1,numPoints) - 0.5;psize = 40;% User wants "all positive to be green and all negative to be red."
% First default to all black;
points_col = zeros(numPoints, 3);% Now find where ALL 3 coords are positive;
allPosIndexes = points_x > 0 & points_y > 0 & points_z > 0;% Set those to green.
points_col(allPosIndexes, 2) = 1;% Now find where ALL 3 coords are negative;
allNegIndexes = points_x < 0 & points_y < 0 & points_z < 0;% Set those to red.
points_col(allNegIndexes, 1) = 1;% Now one octant will be red, one octant will be green
% and 6 octants will be black.
% Now plot.
oldPlot = scatter3(points_x,points_y,points_z,psize,points_col,'filled')xlabel('X', 'FontSize', fontSize);ylabel('Y', 'FontSize', fontSize);zlabel('Z', 'FontSize', fontSize);
Try this:
x1 = randi(9, 5, 1);y1 = randi(9, 5, 1);z1 = randi(9, 5, 1);x2 = randi(9, 5, 1);y2 = randi(9, 5, 1);z2 = randi(9, 5, 1);figure(1)scatter3(x1, y1, z1, 'r', 'filled')hold onscatter3(x2, y2, z2, 'y', 'filled')hold offgrid onlegend('x_1', 'x_2')Do the same for the rest.
