SUMMARY

This discussion focuses on averaging hysteresis curves and calculating their area using MATLAB. Users seek algorithms for averaging multiple x-y curves and inquire about methods for area calculation. A straightforward approach for averaging involves using MATLAB's built-in functions, while numerical integration techniques are recommended for area calculation. Participants suggest either implementing custom algorithms or utilizing existing resources available online.

PREREQUISITES
  • Familiarity with MATLAB programming
  • Understanding of hysteresis curves and their characteristics
  • Knowledge of numerical integration techniques
  • Experience with data manipulation in MATLAB
NEXT STEPS
  • Research MATLAB functions for averaging datasets

Hello everybody

I am new here, so not sure if this is really the right category.

Have recorded numerous hysteresis (x-y) curves experimentally and want to average them all out to get one clean master curve.
Does anybody know if algorithms exist for that in Matlab or in Excel ?

Then a second question , how can the area of a hysteresis be calculated in Matlab?

Many thanks for your feedback

Chris.

Well how complicated do you want to combine your data? A flat average of all the points at particular values could easily just be averaged in matlab.

As for the area, you'll probably want to do some sort of numerical integration technique. You could either write your own, or find one on the internet.
