Please answer in matlab code. 1. (a) Use a for-loop to create arrays x2 and y2 with N+1 unequally spaced points according to the formula x2 = y2 = -cos(pi*(k-1)/N)*2*pi, where N=200,k=1,2...,N+1clear; clc; close all;b)(i)use the meshgrid function on x2 and y2 to create arrays x and y that have the dimensions (N+1) x (N+1)(ii) Preallocate an array z(n,m) where [n,m] = size(x) (iii) Use a nested for-loop and an if-else structure to create an array z according to the formulas:for x < 0, z = 2 + sin(x)*sin(2*y) andfor x >= 0, z = (2 + sin(x)*sin(2*y)*exp(-0.1*x)(c) Use the surfc function to plot the surface z.(i) Set the axis limits so that-n < x < n , and-n < y< T, and 0 < z < zlim: Here zlimshould be the maximum value of z rounded up to the nearest integer. (Hint:use the ceil function).(iii) Your plot should have a title (18 point), axis labels (14 pt), a color bar and an azimuthal angle of +60 degrees and an elevation angle of +30
