Correlation function

  1. Jan 11, 2005 #1
    Have just been reading a paper which talks about a 'height-height correlation function' of a surface. Doesn't provide any equations, but as far as I can make out it seems to be a way of reducing the topography of the surface to a small number of characteristic parameters, which makes sense in the context of the work (AFM study).

    I'd like to know a bit more though. Can anyone provide a simple explanation of the maths behind this, and correlation functions in general? a useful URL that has some details would also help

    H-H correlation function


    Have a look at section 3 of D.T. Pierce et al, J. Magn. Magn. Mat. 200, 290-321 (1999)

    Wow! I hope this person is still around to still need the info, since the question was posted in Jan, 2005!
