MATLAB: How to apply rotation on last few points

Question

I have 5 points but try to rotate the last few points not all

here is the code :

theta = 10;
R = [cosd(theta) -sind(theta) 0 ;
  sind(theta) cosd(theta) 0;
     0 0 1];
initialPoints = [ 0 0 0;
    15 0 0;
    30 0 0;
    45 0 0;
    60 0 0];
Rotation=initialPoints *R; 

the above code work well and rotate all points abut i want to apply rotataion only for last two steps ,can somebody suggest me how can i do that ?

thanks in advance

Answer 1

To rotate only last two points, you can use.

Rotation=initialPoints(end-2:end,:) *R;
