It's tempting to use a 10th-degree polynomial to hit every data point perfectly, but this usually ruins the model's ability to predict new data. Keep it as simple as possible.
It’s not just for 2D lines. You can fit surfaces to 3D data (X, Y, and Z) just as easily. curve fitting matlab download
A GUI that lets you import data, visualize fits, and compare different models (linear, polynomial, exponential, or custom) without writing a single line of code. It's tempting to use a 10th-degree polynomial to
x = [1, 2, 3, 4, 5]; y = [2.1, 3.9, 8.2, 16.5, 26.0]; p = polyfit(x, y, 2); % Fits a 2nd-degree polynomial Use code with caution. Basic Fitting Tool You can fit surfaces to 3D data (X, Y, and Z) just as easily
