Hello Dear, I am pretty new amoung the matlabs users. I need to plot 2 sines waves simultaneouly.
The parameters of the first wave: frequency 0.33 hz and amplitude=4%; second wave: 50 Hz, 1%.
please note that I do not need to build 2 consecutives waves but 2 additive waves superimposed on each other ( 2 wave merging together to create only only wave; like a big wave(the first wave)which contains a tiny sine wave superimposed on (second wave).
thank you in advance for your help.

It is clear what you need, but what is your question?

t=0:.001:3;
plot(t,sin(2*pi*50*t)+4*sin(2*pi*.33*t))
