Finding distance between one fixed point and a range of points.

I have a point, say with coordinates x1,y1. And I have 2 arrays, namely x11 and y11 with the coordinates of the range of points. Want to find the distances between the fixed point and the range of points, and then identify the maximum distance and also plot the line.

Thanks in advance.

%-------------Example----------------------
v=rand(10,2);
n=rand(1,2);
scatter(v(:,1),v(:,2))
hold on
scatter(n(1),n(2),'r')
%--------------------------------------------
[ii,jj]=max(sum(bsxfun(@minus,v,n).^2,2))
m=v(jj,:)
plot([n(1) m(1)],[n(2)  m(2)])
