3 Dimensional convolution in Matlab

  1. Apr 27, 2009 #1
    Hi, I am trying to get the 3 dimensional convolution of a 3 dimensional function with itself using Matlab.



    g(x,y,z) = h1(x,y,z) 3dconvolute with h1(x,y,z)



    As the 3d function is symmetrical in the x,y direction(a circular function), I have reduced the function to a 2 dimensional one.

    g(r,z) = h1(r,z) 3dconvolute with h1(r,z). The matlab command used is conv2(h1,h1); h1 figure attached as func1.jpg

    The center of the h1 function is in the central coordinate of the matrices. The result of the convolution looks queer as attached (func2.jpg). There is a central null region which should be the peak instead(from the simulation result shown in reference)
