The element calculates determinants, linear equation systems and generates matrices. It provides additional basic functionality like faculty, subdeterminant and matrix reduction calculations. Further more an event is implemented to support a progress bar for time intensive operations. The interface is arranged in such a way that the return values of all functions are the resulting arrays. An interlocked call of several functions of the control element, whereby the return values are parameters of the superordinate function and so on, is possible.
