n. In at least one example embodiment of the computer-implemented method, the at least one look-up table is at least in parts determined by the characteristics of a function. In at least one example embodiment of the computer-implemented method, the characteristics of the function determining the at least one look-up table at least in parts is at least one of a slope of the function, a curvature of the function and a zero of the function. In at least one example embodiment of the computer-implemented
