There are no such functions in core MATLAB, but they’re easy enough to write.
This code plots an arc of stars:
circr = @(radius,rad_ang) [radius*cos(rad_ang); radius*sin(rad_ang)]; % Circle Function For Angles In Radians
circd = @(radius,deg_ang) [radius*cosd(deg_ang); radius*sind(deg_ang)]; % Circle Function For Angles In Degrees
N = 25; % Number Of Points In Complete Circle
r_angl = linspace(pi/4, 3*pi/4, N); % Angle Defining Arc Segment (radians)
radius = 1.5; % Arc Radius
xy_r = circr(radius,r_angl); % Matrix (2xN) Of (x,y) Coordinates
figure(1)
plot(xy_r(1,:), xy_r(2,:), 'bp') % Draw An Arc Of Blue Stars
axis([-1.25*radius 1.25*radius 0 1.25*radius]) % Set Axis Limits
axis equal % No Distortion With ‘axis equal’
