Origin's NLFit tool is powerful, flexible, and easy-to-use, allowing the user to fit a non-linear mathematical function to user-selected data. You can fit a portion of your data, an entire data set or multiple data sets simultaneously, and you can choose from one of many built-in non-linear fitting functions or a custom user-defined function.
In addition to the built-in consolidated fitting report sheet, numerical and graphical results from the NLFit tool can be easily combined in an Origin worksheet to create a custom report. The report can automatically update upon data or parameter modification(s), allowing full automation of fitting analysis. Additionally, batch processing of multiple data files is supported.
Global fitting allows you to share parameters when fitting multiple data sets with a function.
