Ran in:
r = 1; %inner radius
xCenter = 5;
yCenter = 5;
theta = 0 : 0.01 : 2*pi;
x = r * cos(theta) + xCenter;
y = r * sin(theta) + yCenter;
plot(x, y, 'LineWidth', 3);
axis square;
xlim([2 8]);
ylim([2 8]);
grid on;
hold on
R = 2; %outer radius
XCenter = 5;
YCenter = 5;
theta = 0 : 0.01 : 2*pi;
X = R * cos(theta) + XCenter;
Y = R * sin(theta) + YCenter;
plot(X, Y, 'LineWidth', 3);
axis square;
xlim([2 8]);
ylim([2 8]);
grid on;
hold off
I need to discretize my ring into equal pieces using nodes (similar to the photo above). How can I go about doing this for any number of segments?

To specify sectors, adjust the starting and stopping angles when you make theta:
theta = 0 : 0.01 : 2*pi;
