write a matlab script to generate the following signal x(n) = 3 r(n-2) − 6 r(n + 1) + 3 r(n) − 4 u(n − 4) in matlab

To generate the given signal x(n) = 3 r(n-2) - 6 r(n + 1) + 3 r(n) - 4 u(n - 4), where r(n) is the unit step function and u(n) is the unit impulse function, you can use the following MATLAB script:

main.m
% Generate the signal x(n) = 3 r(n-2) - 6 r(n + 1) + 3 r(n) - 4 u(n - 4)

n = -10:10; % Define the range of the signal

r = @(n) (n >= 0); % Define the unit step function
u = @(n) (n == 0); % Define the unit impulse function

x = 3 * r(n - 2) - 6 * r(n + 1) + 3 * r(n) - 4 * u(n - 4); % Generate the signal

% Plot the signal
stem(n, x);
xlabel('n');
ylabel('x(n)');
title('Generated Signal');

This script defines the range of the signal, n, and creates anonymous functions for the unit step and unit impulse functions using logical indexing. Then, it uses these functions to generate the signal x according to the given equation. Finally, it plots the signal using the stem function.

Make sure you have MATLAB installed and running to execute this script.
