How do I make a stem plot in MATLAB?

How do I make an input sequence named n with a step of 1, ranging from -10 to 10?

Once I do that, how then do I make a stem plot of a function of n.

Then how to label both the x and y axes and add titles?

Answer 1

[Paulo Silva]

n=-10:10;
a=0*n;
a(n>=0)=1;
stem(a)
xlabel('this is the x label')
ylabel('this is the y label')
title('this is the title')

Answer 2

[RAMA ARAVINTH]

n=-10:10;

a=0*n;

a(n>=0)=1;

stem(a)

xlabel('this is the x label')

ylabel('this is the y label')

title('this is the title')
