                Posted - 07/21/2009 : 3:30:45 PM  Origin Ver. and Service Release (Select Help-->About Origin): 7.5 Operating System:Vista My fitting converges very very slow. I need >11000 iterations to get stable numbers of all the parameter. Is there anyway to improve it or automate the fitting so that I don't have to be around and hit the button for each 100 or 200 iterations? many thanks.

  Could you please read the NLSF object in LabTalk Help for getting a start? You can set nlsf.tolerance to control when the iteration stop. You can also send your script and data to us if it failed.
  Thanks Larry |

                Posted - 07/22/2009 : 12:02:19 PM  Larry,
      Thank you for your reply. Is there a limit for the number I can input there, like 10000? I am also thinking about write a short script by labtalk so it will automatically stop when the parameter don't change. I just don't know how to keep track of the parameters. Please suggest if you have some clue. Thank you very much.

  You can manually enter the maximum number of iterations here:
