Hi there. I am familiar with Origin C. I have written a fitting routine ,say "user", which I can use to fit my data. I have 100 such graphs where I do the same fitting and Origin does remember the last fit so that I dont have to initialize the parameters. I can straight way iterate and get the best fit for that file. Than I move to the next file and so on.
Now what I want is, instead of controlling this manually, I want to fit myself for the first file and i want to write a routine where all the subsequent files will be fitted automatically to the best fit. Can anyone help me with a routine for that ? i hope the question is clear.

Hi AB,

You can loop over all the data in your code for fitting. If you have your own initial parameter values, you can use the NLFitSession::SetParamValues method to set the initial parameter values. Please refer to the examples in Non-linear fitting and Using NLFitSession.
