clear; close all; clc;
```

## 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'); drawnow;
