Let the

         XY_BOUNDARY = [0,70,0,50};
         position = [XY_BOUNDARY(2) - XY_BOUNDARY(1); XY_BOUNDARY(4) - XY_BOUNDARY(3)] .* rand(2,1) ...
               + [XY_BOUNDARY(1);XY_BOUNDARY(3)];

In the above code i get a random number within the specified boundary. Now i want the random point position in a specified boundary as well as on the line connecting two points (x1,y1), and (x2,y2, which are also present within the defined boundary...Please tell me how to do this

Are (x1,y1) and (x2,y2) already stored in your code and you want to find a point on the line between them? Or do you want to generate them randomly from within the boundary and then select a random point on the line between them?

If they're already stored in your code, are they guaranteed to be within the boundary?
