This is very similar to one of questions that I replied to.

How do I plot this in MATLAB?

Here is my script.

n_rays = 16 + 1;
n_circles = 9 + 1;
n_samples = 200;
rays = linspace(0, 1, n_samples)' * exp(1j*linspace(0, 3.686135, n_rays));
interior_circles = linspace(0, 1, n_circles)' * (cos(linspace(0, 3.686135, n_samples)) + 1j * sin(linspace(0, 3.686135, n_samples)));
interior_circles = transpose(interior_circles);
%% plotting
figure;
subplot(1,2,1);
for i_rays = 1:n_rays
    plot(real(rays(:,i_rays)), imag(rays(:,i_rays)),'Color',[88, 140, 102]/ 255)
    hold on;
end
for i_circle = 1:n_circles
    plot(real(interior_circles(:,i_circle)), imag(interior_circles(:,i_circle)),'Color','r')
end
axis square
xlim([-2, 2])
ylim([-2, 2])
grid on;
subplot(1,2,2);
f = @(z) z.*exp(1i*pi/2); % complex function to apply
for i_rays = 1:n_rays
    plot(real(f(rays(:,i_rays))), imag(f(rays(:,i_rays))),'Color',[88, 140, 102]/ 255)
    hold on;
end
for i_circle = 1:n_circles
    plot(real(f(interior_circles(:,i_circle))), imag(f(interior_circles(:,i_circle))),'Color','r')
end
axis square
xlim([-2, 2])
ylim([-2, 2])
grid on;

thankyou so much for the help

[Akansha]

this error is showing on your code

[Angelo Yeo]

Maybe you did not copy and paste the whole code.

[Akansha]

right, thankyou for your help
