Parameters: func (Callable) – The fit function to evaluate. params (Parameters) – lmfit Parameters object containing all parameter values. i (int) – Index of the dataset (0-based). x (ndarray) – Independent variable values. Returns: Evaluated function values for the given dataset. Return type: ndarray
