Origin Ver. and Service Release (Select Help-->About Origin): 9.0
Operating System: Win 7
Good Afternoon,
Im trying to automatise my curve fitting. The Data I want to fit is described with an implict funktion. To do so i wrote this script:
nlbeginr (1,2) EinDiodenModell2 tt;
nlpara;
nlfit;
nlend 1 1;
now I want to be able to edit the Parameter in the Pop up window.
This Code just fits it and gives a Report.
I tried it with "nlpara 1;" because in the help it said i could do so to edit the parameter, but i only get an error message saying: "#Command Error!".
Does anyone know why this does not work or how i can make it work?
thanks |

Hi,
your "nlbegin" has a redundant "r" in the end.
I tried the following script and it works:
//
nlbegin iy:=(1,2) func:=gauss nltree:=tt;
nlpara 1;
nlfit;
nlend 1 1;
//

HI Ikb0221
Yes it does work but not for an implict function, because mine has 2 independent variables, in which case one must use "nlbeginr". But if i use this the Pop up window disappears without editing opportunity right after it popped up and i dont know why. |

| in addition this might not have been very clear, the upper code works perfectly, fits, and gives a Report. Just the editing funcion is lacking functionality |

Hi,
I also tried the following and it works fine in 9.0SR2:
//
nlbeginr irng:=(1,2:3) func:=planeMod nltree:=tt;
nlpara 1;
nlfit;
nlend 1 1;
//
Should use "nlpara 1" instead of "nlpara" only to pop up parameter editing dialog.
Maybe your problem is user defined function related?
But I duplicated circle function to make it a user defined one, and still no problem.

Edit parameter with nlpara; or nlpara1;
