MATLAB Curve and Surface Fitting Program

This MATLAB program implements surface fitting functionality using discrete data points as input. The script is designed to run effectively in cell mode from the MATLAB editor, with the publish to HTML feature offering optimal presentation quality. For older MATLAB versions, users can copy entire code blocks and paste them directly into the command window interface. The program addresses the following application scenarios: - When you possess discrete data points but require a smoother surface representation for better data interpretation - When needing to generate fitted curves based on scattered data points - When working with multiple 3D spatial points that require a continuous surface representation Key implementation features include polynomial fitting algorithms and interpolation methods that construct continuous surfaces from discrete datasets. The program utilizes MATLAB's built-in fitting functions like polyfit for curve fitting and griddata for surface interpolation, providing customizable parameter options for different fitting precision requirements. This tool significantly simplifies the process of converting raw discrete data into analyzable surface models.
