Index of point in matlab plot

x = rand(10,3);
plot3(x(:,1),x(:,2),x(:,3),'R.')
hold on
pause;
y = rand(10,3);
plot3(y(:,1),y(:,2),y(:,3),'B.')

%%%%

After ploting the x and y values, I want to click any point on the plot and it well give the information that perticular point lies in x matrix oy y matrix and tells the point no also respectively.

x = rand(10,3);
y = rand(10,3);

hold on
plot3(x(:,1),x(:,2),x(:,3),'R.')
plot3(y(:,1),y(:,2),y(:,3),'B.')

idx = knnsearch(x,y) ; 


position_of_y = (1:size(y,1))' ;
nearest_of_y_in_x = idx ;
T = table(position_of_y,nearest_of_y_in_x) ;

text(y(:,1),y(:,2),y(:,3),num2str(position_of_y))
text(x(:,1),x(:,2),x(:,3),num2str(nearest_of_y_in_x))

What is table ?

T = table(position_of_y,nearest_of_y_in_x) ;

It is kind of representing data. Read about it.
