Description
The arrays are defined starting with 0. The element 0 is ignored. For this reason, only valid data from 1 is used in a for statement. The result is a two-dimensional array that contains at least one empty variant at each point in time. If there are several values in an interval step, the result is formed taking into account the statistical function of the avStatFct array.
