Matlab file for LLS and LMS for simple problem solving

Matlab functions implementing non-parametric local linear smoothing (LLS) for one-dimensional curve fitting: yi = f(xi) + ei for i = 1, 2, ..., n. The toolbox contains: (i) the usual LLS estimator, see e.g. [1] (ii) a jump-preserving (two-sided) LLS

Write a MATLAB function lls_rd.m (rd stands for rank de… cient) to solve the LLS problem
