LMFit

LMFit is a Python library providing a high-level interface for non-linear least-squares minimization and curve fitting. It extends and builds upon `scipy.optimize` by introducing `Parameter` objects, which simplify the process of defining, constraining, and managing fitting variables. Currently at version 1.3.4, `lmfit` maintains an active development cycle with regular releases addressing bug fixes, new features, and dependency updates.
