Syntax

a=randInCircle(siz);

Description

This function generates a matrix or array of uniformly distributed random points inside a circle with radius R.

Plot settings for examples

markerSize=35;
lineWidth=3;
fontSize=35;

Example

n=1000; %Number of points
R=2; %Radius of the circle
V=randInCircle(n,R); %Uniformly sampled points inside the circle

Visualization

%Create circle coordinates to visualize circle curve
t=linspace(0,2*pi,100)';
vc=R.*[cos(t) sin(t)];

cFigure; hold on;
hp1=plotV(V,'k.','MarkerSize',markerSize);
hp2=plotV(vc,'b-','LineWidth',lineWidth);
axis tight; axis equal; box on; grid on;
view(2);
set(gca,'FontSize',fontSize);
legend([hp1 hp2],{'Uniformly distributed circle interior points','Circle boundary'},'Location','NorthOutside');
