MATLAB program for impulse waveform generation

Program Code

n=-5:5;
y=[zeros(1,5) 1 zeros(1,5)];
stem (n,y);
xlabel ('Time');
ylabel ('Amplitude');
title ('Impulse Waveform');
grid on;

Output

Explanation of Program Code 

clc;

It clears all input and output from the Command Window display giving clean screen. It removes items from workspace, freeing up system memory. After using clc, the scroll bar cannot be used to see the history of functions, but still the up arrow can be used to recall statements from the command history.

clear all;

It removes all variables from the workspace. This frees up system memory.

close all;

It deletes all figures whose handles are not hidden.

n=-5:5;

This command creates vector n.

Vector n is given by

n= [-5    -4    -3    -2    -1     0     1       2       3        4        5]

Here vector n is used as x axis

y=[zeros(1,5) 1 zeros(1,5)];

This command creates impulse waveform.

stem (n,y);

This command plots n versus the columns of y as stems. . n and y must be vectors or matrices of the same size. Additionally, n can be a row or a column vector and y a matrix with length(n) rows.

This command makes impulse waveform appear on the screen.

xlabel ('Time');

It labels the x-axis as 'Time'. Each axes graphics object can have one label for the x-, y-, and z-axis. The label appears beneath its respective axis in a two-dimensional plot.

ylabel ('Amplitude');

It labels the y-axis as ' Amplitude. '

title ('Impulse Waveform');

It outputs the phrase  'Impulse Waveform' above the figure at the top.

grid on;

It adds major grid lines to the current axes.
