MATLAB: Tell me the code for how to place scatterrers in a cylindrical volume

creation of cylinder

place different scatterrers in a cylindrical volume

Best Answer

radius = 5;
height = 18;
N = 1000;
r = sqrt(rand(1,N)) * radius;
th = rand(1,N) * 2 * pi;
h = rand(1,N) * height;
[X, Y, Z] = pol2cart(th, r, h);
scatter3(X, Y, Z)

MATLAB: I need help to plot circle around the points and these points are in a circle. please response

n=10; % number of points that you want
    center = [2 ,2]; % center coordinates of the circle [x0,y0] 

    radius = 10; % radius of the circle

      angle = 2*pi*rand(n,1);
      r = radius*sqrt(rand(n,1));
     X = r.*cos(angle)+ center(1);
     Y = r.*sin(angle)+ center(2);
     plot(X,Y,'.r')
     hold on
     %%Draw circle 
     R = 1. ;  % radius 
     th = linspace(0,2*pi) ;
     for i = 1:length(X)
         x = R*cos(th)+X(i) ;
         y = R*sin(th)+Y(i) ;
         plot(x,y,'b')
     end
     hold on
     center = [2 ,2]; % center coordinates of the circle [x0,y0] 
    radius = 10; % radius of the circle
    angle = 0:.01:2*pi;
    r = radius;
       X = r.*cos(angle)+ center(1);
       Y = r.*sin(angle)+ center(2);
     plot(X,Y,'.b')

MATLAB: I want an exponent to be displayed as an actual exponent not just x^2 for example.

h = msgbox(sprintf('The volume of the cylinder is %.2f cm^3\nThe surface area of the cylinder is %.2f cm^2',volume,surf));
th = findobj(h, 'type', 'text');
th.Interpreter = 'tex';
waitfor(h);
