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

To rotate only last two points, you can use.
Rotation=initialPoints(end-2:end,:) *R;

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(end,:)*R;
R = initialPoints ;
R(end,:) = Rotation ;
I = initialPoints ;
plot(I(:,1),I(:,2),'LineWidth',10) ;
hold on
plot(R(:,1),R(:,2),'LineWidth',10) ;
