Shows the content of matrices, that are given as two-dimensional arrays. This can be done both in runtime mode and in design mode. The element itself is invisible. It shows a form to give out the matrix content. The matrix display for example serves debugging purposes.

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 database can describe files to make it easy to overview their contents and to search for special files by the description typed in. The files are stored separately, where they were originally located. Nevertheless they can quickly be viewed by the functionality provided in the database form.
