Curve Fitting Implementation in MATLAB

Resource Overview

A self-developed curve fitting program for reference and collaborative learning

Detailed Documentation

I have developed a curve fitting program designed to provide reference and learning resources for those needing assistance in this area. The program implements multiple curve fitting methods including least squares approximation, Newton's interpolation method, and goodness-of-fit evaluation metrics. The implementation features automated data processing capabilities that efficiently handle large datasets through vectorized operations and optimized memory management. Additionally, the program includes comprehensive documentation and usage instructions with code examples demonstrating key functions like polyfit() for polynomial fitting and fminsearch() for nonlinear optimization. Technical explanations cover algorithm selection criteria and convergence analysis for different fitting scenarios. This program aims to support better understanding and research in the field of curve fitting through practical MATLAB implementation.
