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
• J. Šaliga, S. Csernok C-language function class
  for signal processing at ADC testing, proc. of
  ADDA EWADC 2002 conf., Prague, pp. 235 - 238
• Access in the present jan.saliga_at_tuke.sk or
  http//meas-lab.tuke.sk
