Does anyone helpe me to explain wht is this meant by each step? Thanks

function value = random_pi()

%creates 10,0000 points N = 100000; % Numbers of input point X = -1+2*rand(1,N);% X vector of N values Y = -1+2*rand(1,N); % Y vector of N values j =1; hold on; viscircles([0,0],1); z=3; %size

for i=1:N if (Y(i)^2+ X(i)^2)<1 % check point whether falls inside the circle. x(j) = X(i);% This vector contains x points which falls in circle y(j) = Y(i);% This vector contains y points which falls in circle j = j+1; %scatter(X(i),Y(i),z,'filled');

end end

scatter(x,y,z,'filled'); hold off; pi_value = (j*4)/N; % calculate value of pi disp(pi_value); value = [x,y]; end
