Hi, i would like to know how to add a Gaussian noise distribution of SD 1% and 0 mean to a uniform grid consisting of particle pairs. (P1x,P1y),(P2x,P2y) contain the location of the points in my grid and they are data taken from a PIV Simulation. so should i add use the command awgn(x,0.1) where i replace x with the the coordinates of the points? Thanks

y = awgn(x,snr)
adds Gaussian noise. Perhaps you need to keep SNR bigger. 0.1 is too low.
