I'm starting in Matlab and I have to code what I think it is centred loops spreading in different directions. Just like the picture I added. This represents a desert ant lookig for its home and each loop adds uncertainty. Any guidance on where to start would be appreciated.

hello

try this

circles_radius = 1;
radius_noise_amplitude = 0.05;

center_radius = 2;
center_radius_noise_amplitude = 0.25;

nb_of_circles = 25;

figure(1);
axis square
hold on

for ci = 1:nb_of_circles
    
    center(1) = center_radius.*cos((ci-1)*2*pi/nb_of_circles)+center_radius_noise_amplitude*randn;
    center(2) = center_radius.*sin((ci-1)*2*pi/nb_of_circles)+center_radius_noise_amplitude*rand;
 
    [XData,YData] = circle(center,circles_radius,radius_noise_amplitude);
    plot(XData,YData);
end
    
hold off


%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

function [XData,YData] = circle(center,radius,radius_noise_amplitude)
points = 100;
theta = 0:2*pi/(points-1):2*pi;
XData = center(1)+radius.*cos(theta)+radius_noise_amplitude*randn(size(theta));
YData = center(2)+radius.*sin(theta)+radius_noise_amplitude*randn(size(theta));

end
