For the modelling, feedforward and feedback control of nonlinear processes one uses frequently two- and/or multidimensional characteristics. Such characteristics can be represented effectively by locally generalizing storage methods. By three different examples and their further development it is shown in this paper, that very different approaches are possible and that taking into account the inherent advantages and disadvantages one should choose the most appropriate method according to the envisaged application. Part II deals as a third approach with a method, which has been inspired by some mathematical technique to represent arbitrarily formed surfaces in the three dimensional space and gives also a summary of both parts of the paper.
