MATLAB: Count in a loop

countloops

Imagine a square with sides of 2 meter. In the centre is point M, at (0,0). We randomly throw darts at this square, which all hit at some location p on the square (uniform distribution). Next, we count the number of ‘hits’. Each dart is a hit when the distance from p to M is less than or equal to 1.
I have this code I dont know how to count the number of p that is less than or equal to 1
for i=1:100;
p_x= -1+(1+1)*rand;
p_y= -1+(1+1)*rand;
p = sqrt((p_x)^2 + (p_y)^2)
end;

"I have this code I dont know how to count the number of p that is less than or equal to 1"
count=0;
for i=1:100
    p_x= -1+(1+1)*rand;
    p_y= -1+(1+1)*rand;
    p = sqrt((p_x)^2 + (p_y)^2)
   if p<=1
   count=count+1;
   end
end
fprintf('The p count is (when p<=1): %d',count);
