Draw lines from one point to the all others

Can someone help me to draw lines between a central point to the all others. The points are created randomly, lets take 5 points.

xy = rand(5, 2);

distances = pdist2(xy, xy)

S = sum(distances)

This code will give all sum of distances between the points, now the point having minimum distance will be taken as central. I want to connect the other points with the central one. Something like this, i draw this in paint.

If I understand correctly what you want to do, this works.

The Code —

xy = rand(5, 2);
centrd = mean(xy);                                                                  % Calculate Centroid

[dist1,idx1] = pdist2(xy, centrd, 'euclidean', 'Smallest', size(xy,1));             % Distances From Centroid
centre_point = xy(idx1(1),:);                                                       % Point With Shortest Distance To Centroid
[distances,idx2] = pdist2(xy, centre_point, 'euclidean', 'Smallest', size(xy,1));   % Distances From Centre Point
Distance_Sum = sum(distances);                                                      % Sum Of Distances To Centre Point

figure(1)
plot(xy(:,1), xy(:,2), 'pg', 'MarkerSize',10, 'MarkerFaceColor','g')
hold on
plot([repmat(centre_point(1),size(xy,1),1) xy(:,1)]', [repmat(centre_point(2),size(xy,1),1) xy(:,2)]')
hold off
grid
text(centrd(1), centrd(2), sprintf('\\Sigma \\itdist\\rm = %.4f',Distance_Sum), 'FontSize',10)

The Plot —

Thank you very much Star Strider, though you have done it in a different way but the result is same

My pleasure.
