Hello all , I am updating position of cylinder using slider , But I want to see only updated shape but its showing them all , means all previous ones also . used code under the slider function is -
hold on
[xc,yc,zc] = cylinder(10);
zc(2,:)=30;
ab = surf(yc+x_pos,zc+y_pos,xc+z_pos,'Facecolor','b');
dir=[0 0 1];
rotate(ab,dir,90);
dir=[1 1 0];
hold off
end
where x_pos , y_pos and z_pos updates the position of cylinder.

You should check the Interruptible and BusyAction properties of the slider object. Sliders often call back multiple times quickly, which could result in calls interrupting each other, interfering with your hold on / hold off logic.
You know that you should be generating your object ahead of time and then your slider should be changing its position coordinates without recreating the object.
