MATLAB: How i can draw a sector of a circle in matlab

circledrawpieplotsectorsector's center

I want to draw a sector of a circle. The angle and the coordinate of sector's center are specified but the direction of the angle is random. i should mention that i need this pie to be a complete one, not just the curved part. like one of the pieces in this command:
pie([2 4 3 5],{'North','South','East','West'})
could anyone help me for the code please?

Let r be the circle's radius, P0 = [x0,y0] be its center, and theta be the required angle in radians.
   a1 = 2*pi*rand;  % A random direction
   a2 = a1 + theta;
   t = linspace(a1,a2);
   x = x0 + r*cos(t);
   y = y0 + r*sin(t);
   plot([x0,x,x0],[y0,y,y0],'y-')
   axis equal
