I was asked to create a function that plots points randomly in a [0,1]x[0,1] square. Then to estimate Pi based on the number of points that fall within the 1st quadrant unit circle.
- So: points within the unit circle / points total.
- This should roughly equal pi.I'm stuck on how to create that unit circle boundary and how to look at the # number of points within boundary.This is what I have so far:
function estpi=estimate(npts)
x=zeros(1,npts);
y=zeros(1,npts);
for i=1:npts
x(i)=rand(1);
y(i)=rand(1);
end
plot(x,y,'o')
end
%number of points inside circle/ total points
