Points Inside polygone 1.0

Find those points (xi,yi) who are inside the polygone defined by the vectors (x,y).Syntax: [xin,yin,Ind]=Inside(X,Y,xi,yi)where Ind is the index of (xi,yi) that are inside the polygone Example: %--- create polygone (x,y) phi=linspace(0,2*pi,50); X=(1+0.2*sin(6*phi)).*cos(phi); Y=(1+0.2*sin(6*phi)).*sin(phi); %--- random points (xi,yi) Nr=20; xi=randn(1,Nr);yi=randn(1,Nr); [xin,yin,Ind]=Inside(X,Y,xi,yi); %--- plot plot(X,Y,X,Y,'.',xi,yi,'ro',xin,yin,'b.');axis equal;
