how can i plot a sine wave with different peak amplitudes

how to plot a sine wave with different peak crests and troughs ?

Answer 1

[Joseph Cheng]

you can add different sine waves together that have different amplitudes and periods. ex:

t = 0:.1:100;

amp = zeros(size(t));
for ind = 1:5
   amp = rand(1)*sin(2*pi*t/randi(20,1,1)+20*randi(5))+amp;
end
figure,plot(t,amp)

just a flavor since i don't know exactly what constrains you have on the sine wave.

t = 0:.1:100;

amp = zeros(size(t));

for ind = 1:5

amp = rand(1)*sin(2*pi*t/randi(20,1,1)+20*randi(5))+amp;

end

figure,plot

(t,amp)

@BIBIN SOORAJ R, your answer looks like you just copied it from @Joseph Cheng's answer. Is anything different (other than you introducing the error of splitting the last line into two)?
