I wamt to plot 3 spheres with different colours. But i am unable to do it. I am sharing the code as well. Thank you for your help.
x_min = 5; x_max = 45; y_min = 5; y_max = 45; z_min = 5; z_max = 45;
centre_x(1) = x_min + rand(1)*(x_max-x_min);
centre_y(1) = y_min + rand(1)*(y_max-y_min);
centre_z(1) = z_min + rand(1)*(z_max-z_min);
radius(1) = 4+rand(1)*(5-4);
volume = (4/3)*pi*radius(1)^3; i=2; iteration=0;
plot_sphere(centre_x(1),centre_y(1),centre_z(1),radius(1));
%% plot_sphere function
function [] = plot_sphere(xi,yi,zi,r)
[x, y, z] = sphere;
x = x.*r;
y= y.*r;
z = z.*r;
surf(x+xi, y+yi, z+zi);
%colormap summer
mymap = [1 0 1];
%cmap =
colormap(mymap);
hold on;
axis equal
end

You can only use one colormap per axes. You need to use different axes, or you need to supply "CData" in the surf() call passing rgb color data

mymap = [1 0 0];
