Version: Origin 7.5G Pro RS 3
Operating System: Windows 7
Hey,
I would like to fit my data in a worksheet with a monoexponential decay (the x-axis data is always the same and there are different y-axis columns). All datasets should be fitted monoexponetially and I would like to save the fitting parameters in a different worksheet.
So far, I know that the command "run.section(fit, expdecay1)" will give the fitting. But I don't know how to pick the column for fitting and save the parameters. Someone could help me?
P.S: I'm pretty new to Laptalk programming, so please keep it simple.
Thank's for helping! |

You have to make the data worksheet active with something like:
window -a Data1;
You can select a column for fitting:
worksheet -s 2 0 2 0; // This select all of column 2
Assuming you have already created a three column worksheet named Results and you are using a variable named iRow to keep track of added results, run this script immediately after each fit:
%(Result,1,iRow)=P1;
%(Result,2,iRow)=P2;
%(Result,3,iRow)=P3;
iRow++;

Your script is just working fine, greg! Thanks a lot!
One more question: Is it also possible to print the errors of the fitting parameters in that worksheet as well? |

| Use PE1, PE2 and PE3 to get the errors of the parameters. |

OK, now I know how to handle the data.
Thank you one more time! |
