Built-In Curve Fit Functions
- Gaussian peak
- Lorentzian peak
- Exponential with X offset constant
- Double Exponential with X offset constant
- Double Exponential
- Hill Equation
All built-in nonlinear fit functions feature automatic initial guess generation.
Override automatic initial guesses with your own.
Hold any fit coefficient. For instance, hold constant term in line fit to fit a line through the origin or any other y-intercept.
