Damping Factor for the Least-Squares Method of Optical Design

Webexample given in the previous lecture, we could have ﬁtted a least-squaresquartic to the original “noisy” data. The effect of using a higher-degree polynomial is to give both a higher degree of tangency at and a sharper cut-off in the amplitude response. An example of a simple moving-average ﬁlter is the Hanning ﬁlter , for which: WebIn this paper, we present a tutorial report of the literature on the damped-least squares method which has been used for computing velocity inverse kinematics of robotic manipulators.
