Thank your  for your replies! I will study everything you told me.

Let's forget the case of 6 variables and  let's consider tha general case,where I have n variables and I compute the covariance matrix (n x n). Using the matlab funuction "size" I can find n. How can I compute the 4th-order-moments matrix now?Can someone write the matlab code according to the equation I gave you? 

The matrix should be 2-dimensional n^2 x n^2  because I have to multiply it with another matrix of the same dimensions.

Thank you very much guys...
