That is a little difficulty to explain. In short: I am calculating a Gaussian function for an image which describes the probability densities of the colour distribution. This is used for image segmentation. As a part of this calculation a covariance matrix (I don't know if that's the proper term in english) is needed. In order to calculate the covariance matrix I need the entry-by-entry product. (this explanation might not be totally correct - I am unfortunately not the mathematical master mind of this project)
