I have a sector defined by the following code.
x0=12;
y0=13;
theta =30;
r=3
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],'k-')
I want to check if a point, say [12.5 11.5] lies within the sector defined. Thanks in advance.

YOu should be having a set of points for sector and the points for circle. Use inpolygon to know whether these points lie inside or outside the given circle. Read about inpolygon.
