Does anybody know how to plot kappa distribution function in plasma physics (in Mathematica or Matlab)? enter image description here

  • Have you tried using the "Plot[ K[x] , {x,-4,4}]"? – peep Nov 14 '22 at 08:27
  • @peep no, i did it right now, but it doesn't work – lia Nov 14 '22 at 08:30

    Are you asking how to calculate the kappa function? If you're just asking how to operate the software then that is off topic as it isn't a question about physics. – John Rennie Nov 14 '22 at 08:42
  • john-rennie no my question is not related to the software. regardless of the program, i have problem in determining the function, physically speaking. Thank you anyway. – lia Nov 14 '22 at 08:46
  • Please check my answer, I have a feeling it will not be what you want. Could you clarify exactly what is the problem? Also adding the reference for the picture would have been nice! – peep Nov 14 '22 at 09:35
  • @peep actually I compared this with my calculations and something seems to be wrong. I will add the reference here. https://munin.uit.no/bitstream/handle/10037/239/thesis.pdf?sequence=1&isAllowed=y pages 6-7 – lia Nov 14 '22 at 15:20
  • @peep Thank you so very much, I really appreciate that – lia Nov 14 '22 at 15:22

This seems to reproduce the plot you've sent. plot
