Help I want the MATLAB CODE

[SOWHAT0819]

Let's manually compute y = 2x(−n + 1) using the given sequence x · {−4, 3, 4, 3, −5, 1, −5, −2, −5, 4, 1}: y = 2x(−n + 1)
y(0) = 2x(−(0) + 1) = 2x(1) = 2 × 4 = 8
y(1) = 2x(−(1) + 1) = 2x(0) = 2 × 3 = 6
y(2) = 2x(−(2) + 1) = 2x(−1) = 2 × 4 = 8
y(3) = 2x(−(3) + 1) = 2x(−2) = 2 × 3 = 6
y(4) = 2x(−(4) + 1) = 2x(−3) = 2 × (−5) = −10
y(5) = 2x(−(5) + 1) = 2x(−4) = 2 × 1 = 2
y(6) = 2x(−(6) + 1) = 2x(−5) = 2 × (−5) = -10
y(7) = 2x(−(7) + 1) = 2x(−6) = 2 × (−2) = −4
y(8) = 2x(−(8) + 1) = 2x(−7) = 2 × (−5) = −10
y(9) = 2x(−(9) + 1) = 2x(−8) = 2 × 4 = 8
y(10) = 2x(−(10) + 1) = 2x(−9) = 2 × 1 = 2

I want the matlab code to get the signal sketch!!!

Here is the MATLAB code to plot the signal y based on the manual computation you provided:

% Given sequence x(n)
x = [-4, 3, 4, 3, -5, 1, -5, -2, -5, 4, 1];

% Compute y(n) based on the formula y(n) = 2x(-n + 1)
n = 0:length(x)-1;
y = zeros(size(x));

for k = 1:length(x)
    y(k) = 2 * x(max(1, -k + 2));
end

% Plot the signal
stem(n, y, 'LineWidth', 1.5);
xlabel('n');
ylabel('y(n)');
title('Plot of the Signal y(n) = 2x(-n + 1)');
grid on;

You can copy and paste this code into a MATLAB script file or the MATLAB command window to generate the plot of the signal y based on the computed values.
