technical-scientific spreadsheet

Dear readers,

I would like to draw your attention to a technical-scientific spreadsheet
application I programmed (in German).
Among other things, it can process two or more functions defined at non-identical
x-coordinates, perform low-pass filtering, interpolate datasets using non-
overshooting Akima splines, and generate uncorrelated and partially correlated
random numbers.

Here is a description and a download site:  www.umark.de/twtab_descr_d.html

I welcome your feedback and suggestions.

Regards,
Udo Mark
