NumberNewPoints = 3;
xvals = linspace(2, 10, NumberNewPoints+2);
yvals = linspace(5, 15, NumberNewPoints+2);
pts = [xvals(:), yvals(:)];
Now the points are the rows.

dear watler according to your code
NumberNewPoints = 3;
xvals = linspace(2, 10, NumberNewPoints+2);
yvals = linspace(5, 15, NumberNewPoints+2);
pts = [xvals(:), yvals(:)];
but I choose NumberNewPoints = 1;
so, the new created point is (6,10) how can I move this created point between p1(2,5) and p2(10,5).. that means i want to move this created point to p1 at first state , and move the created point to p2 at a second state,and the movement time is 2. But this movement do not exceed P1 and p2
thanks a lot

pts(1,:) %x,y for starting point
pts(2,:) %x,y for intermediate point
pts(3,:) %x,y for final point

out = ([10,15]-[2,5])*(2*rand-1)+[2,5]
