Question
I was trying the Wavelet toolbox; wherein they have the file 'noisysig.mat'. It contains three variables s1, s2 and x. I understand that these contain the normal and the noisy signal but I wish to know how to create such noisy signals so that I can practice denoising with some other signals. How do I do that?

N=1000; x=linspace(0,2*pi,N); y=sin(x); y2=randn(1,N); y3=y+y2*.1; subplot(2,1,1);plot(x,y) subplot(2,1,2);plot(x,y3)
