Note: I need MATLAB code ASAP please
2. Apply the function compute Lebesgue function(xi,x) to the four cases of evenly- and unevenly-spaced grids you studied in Exercise 2. To this end, set x to be a vector of 1000 evenly-spaced nodes in [-1,1 (including endpoints), and write a function function [L1,L2 ,L3 ,L4,el,e2,e3,e41-Lebesgue-constant sand-errors () that plots the Lebesgue function (4) for the aforementioned four cases (4 different Figures) The function should also return the value of the
