note :- do work without any errors !

Practice part: Go through Chapter 3 pages of the textbook for the steps one needs to take when using the MATLAB Coder. Also, watch the video made and posted on eLearning describing these steps. As described in the textbook, generate the following signals in a MATLAB function and name it Lab4_practice: x = e-24,0 st s 10 0, Osts1 h = {1, 1 sts3 lo, 3sts 10 This function has one input Delta, which is the time step or time interval between samples, and three outputs x, h, and y (y is the element-wise multiplication of x and h) as follows: function (x, h, y] =Lab4_practice(Delta) As described in the textbook, write a MATLAB testbench code (name it Lab4_practice_testbench) to call this function and plot the three output arrays or signals. Then, use the smartphone shell provided (named Lab4_practice_shell) to make a corresponding smartphone app. Problem part: Do not skip the practice part, i.e. do not jump into the problem part without having done the practice part as otherwise you will face difficulties doing the problem part. problem1 Write a MATLAB function and testbench to obtain the first 10 elements of the following difference equation (name the MATLAB function and testbench Lab4_probleml and Lab4_probleml_testbench, respectively): y[n] = 0.5y[n 1] + x[n], x[0] = 1 The function Lab4_probleml needs to be in the following form: The function Lab4_probleml needs to be in the following form: function y = Lab4_probleml(x, n) x: Input signal values n: Number of time steps y: Output signal values Use the MATLAB Coder and the shell provided (Lab4_probleml_shell) to create a smartphone app displaying the first 10 elements of the difference equation
