is that code matching the requirements of the problem or not ?

```

% Define the function g[n]

n = -4:5;

g = [-3 -3 2 2 0 0 0 -3 -3 -3];

% Plot g[n]

subplot(2,2,1);

stem(n, g);

title('g[n]');

xlabel('n');

ylabel('g[n]');

% Plot the even part of g[n]

ge = g;

subplot(2,2,2);

stem(n, ge);

title('Even part of g[n]');

xlabel('n');

ylabel('ge[n]');

% Plot the odd part of g[n]

go = zeros(size(g));

subplot(2,2,3);

stem(n, go);

title('Odd part of g[n]');

xlabel('n');

ylabel('go[n]');

% Plot g[2n]

n2 = -2:2;

g2n = [2 0 0 -3 -3];

subplot(2,2,4);

stem(n2, g2n);

title('g[2n]');

xlabel('n');

ylabel('g[2n]');

% Plot g[n/2]

n2 = linspace(12,22,3);

gn2 = [-3 -3 -3];

subplot(2,2,4); hold on;

stem(n2, gn2);

title('g[n/2]');

xlabel('n');

ylabel('g[n/2]');

```

No. The function is defined over real values but your code is only over integers.

[Raouf]

% Define the function g(n)

g = @(n) -3*(n >= -4 & n <= 2) + 2*(n >= 3 & n <= 5);

% Plot g(n)

n = -10:10;

stem(n, g(n));

title('Plot of g(n)');

xlabel('n');

ylabel('g(n)');

% Plot even part of g(n)

ge = @(n) (g(n) + g(-n))/2;

stem(n, ge(n));

title('Plot of even part of g(n)');

xlabel('n');

ylabel('ge(n)');

% Plot odd part of g(n)

go = @(n) (g(n) - g(-n))/2;

stem(n, go(n));

title('Plot of odd part of g(n)');

xlabel('n');

ylabel('go(n)');

% Plot g(2n)

n2 = -5:5;

stem(n2, g(2*n2));

title('Plot of g(2n)');

xlabel('n');

ylabel('g(2n)');

% Plot g(n/2)

n3 = -20:20;

stem(n3, g(n3/2));

title('Plot of g(n/2)');

xlabel('n');

ylabel('g(n/2)');

is it right now ?

[Walter Roberson]

No. What part of your code would be able to calculate the output for n = sqrt(5) for example?
