Function Fitter
Read full descriptionHide full description
Function curve fitting using custom function that you enter. Reads data values either from file or manual entry, and tries to fit your function to the data by adjusting 1 to 4 parameters for a least-squares best fit. For enjoyment only, NOT for serious data needs. This is minimalist by design with no ads, no in-app purchases, no bells and whistles, and no fancy moving graphics to distract you, just fun. Note: Entertainment value only, fun using different parameter starting values.
