Structure Functions in MATLAB
 
Hello All CFD people

Anyone out there to help me with getting a MATLAB code to produce a structure function of a real-time stationary signal? I know the structure function can be done in a similar way to auto correlation function, where

if R(s) = < u(t) u(t + s) >, is the auto correlation, then

D(s) = < [u(t + s) - u(t)]^2 > is the second order structure function.

Anyone could send through a sample MATLAB code - would help heaps!!

Thank you!
