matlab program for sine wave generation(Continous and discrete)

Program

% continous sine wave
t=0:.1:10;                                   %create an array t 

a=input('enter the amplitude');
f=input('enter the frequency');
y=a*sin(2*pi*f*t);                      %calculation of sine wave
plot(t,y);                                     %plot the value of t against y
title('continous sinewave');      % title of the graph
xlabel('time');
ylabel('amplitude');

output

% discrete sine wave
clc;                                         %clear command window
t=0:.1:10;                               %create an array t starting from 0 and .1 is the increment and 10 final value
a=input('enter the amplitude');
f=input('enter the frequency');
y=a*sin(2*pi*f*t);                    %calculation of sine wave
stem(t,y);                                 %discrete plot the value of t against y
title('discrete sinewave');         % title of the graph
xlabel('time');
ylabel('amplitude');
