Question

Assume that y is a column vector with ten elements, write matlab code that will create a stem plot of the vector starting at a horizontal axis value of 1. Add code that will create the stem plot of the vector starting at a horizontal axis value of 0. Create additional code that creates a stem plot but plots y at every other horizontal value (i.e., 0, 2, 4, etc)

Answer 1

% Program -1

clc;
close all;
clear all;
y=[0;1;2;3;4;5;6;7;8;9] %column vector with ten elements
x=1:1:10;
stem(x,y);

output:

y =

0
1
2
3
4
5
6
7
8
9

2345678910

% Program -2

clc;
close all;
clear all;
y=[0;1;2;3;4;5;6;7;8;9]
x=1:1:10;
subplot(2,1,1)
stem(x,y);
x1=0:1:9;
subplot(2,1,2)
stem(x1,y);

output:

G- GH NHO 900 + NO 900 + NO

% Program -3

clc;
close all;
clear all;
x=0:1:9;
y=2*x;
stem(x,y)

output:
