Introduction
Existing software: end user application: LabVIEW
J. Blair: “Sine-fitting software for IEEE Standards 1057 and 1241” IMTC’99. Proceeding, Venice, Italy, May 1999. pp. 1504-6.
Matlab J. Márkus, I. Kollár: “Standard framework for IEEE-Std-
1241 in Matlab”, IMTC’01 Proceeding, Budapest, Hungary, May 2001, , pp. 1847 – 1852

Why such a library? Open source library was missing C language: very common, simply transferable on
other platforms and languages Developing tool: LabWindows/CVI by NI in form of
Instrument driver Based on DYNAD, useable for IEEE, added special
functions Introduced:
