Hi,
The stem plot of the sequence ( u(n-3) - u(n-6) ) represents a difference of two unit step functions, which essentially creates a rectangular pulse starting at ( n = 3 ) and ending just before ( n = 6 ). You can use “stem” function to plot the stem plot. Refer to the below example code for a better understanding:
% Define the range of n
n = 0:10;
% Define the sequence
x = (n >= 3) - (n >= 6);
% Plot the sequence using stem
stem(n, x, 'filled');
% Add labels and title
xlabel('n');
ylabel('x[n]');
title('Stem Plot of the Sequence u(n-3) - u(n-6)');
grid on;
For more information on the “stem” function refer to the below documentation:
