MATLAB code with comments to generate common time signals

Hello, friends here I am providing MATLAB code for generating different common continuous time signals such as sine wave, cosine wave, square wave, ramp wave and dc signal, with the comments for each code to learn what each code stands for. So let's go...!!

Here is the M-code with comments:

This will be your input to MATLAB window:

clc                              %clear screen

a=6;                             %defined amplitude

t=0:.01:10;                      %time interval=(initial:diff:final)

f=9;                             %defined frequency

y1=a*sind(2*pi*f*t);             %formula of sine function

subplot(3,2,1)                   %plotting at first place out of 6

plot(t,y1)                       %continues signal of sine wave

xlabel('time')                   %defining X-axis                  

ylabel('amplitude')              %defining Y-axis          

title('sine wave')               %Title of sine Graph  

grid on

y2=a*cosd(2*pi*f*t);             %formula of cosine  function 

subplot(3,2,2)                   %plotting at second place out of 6     

plot(t,y2)                       %continues signal of cosine wave       

xlabel('time')                   %defining X-axis                  

ylabel('amplitude')              %defining Y-axis          

title('cosine wave')             %Title of cosine Graph

grid on

f1=0.5;                          %defined frequency

y3=a*square(2*pi*f1*t);          %formula of Square wave

subplot(3,2,3)                   %plotting at third place out of 6

plot(t,y3)                       %continues signal of square

xlabel('time')                   %defining X-axis                  

ylabel('amplitude')              %defining Y-axis          

title('square wave')             %Title of square Graph

grid on

Y4=t;                            %formula of ramp wave

subplot(3,2,4)                   %plotting at fourth place out of 6

plot(t,t)                        %continues signal of RAMP

xlabel('time')                   %defining X-axis                  

ylabel('amplitude')              %defining Y-axis          

title('ramp')                    %Title of ramp Graph

grid on

y5=2;                            %formula of dc signal

subplot(3,2,5)                   %plotting at fifth place out of 6

plot(t,y5)                       %DC signal

xlabel('time')                   %defining X-axis                  

ylabel('amplitude')              %defining Y-axis          

title('dc')                      %Title of DC Graph

Your output will look like this each graph shown here.
