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.

@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)?
